You were having a great time. Then they ran across the road to catch the bus, arms flailing, and something in you switched off. Nothing about them changed, but suddenly the thought of kissing them feels wrong.
That is the ick. It is sudden, often irrational, and very common. It is also one of the least understood feelings in dating, partly because people talk about it mostly as a joke.
Where the Word Comes From
The phrase was used in the late 1990s on the TV show Ally McBeal, where a character describes suddenly being repelled by someone she liked. It went mainstream again with the UK dating show Love Island in the late 2010s, and on social media in the 2020s, where lists of icks (pulling a suitcase badly, clapping when a plane lands, saying "my lady") became their own genre.
What made it stick is that it named something people had felt but struggled to describe: attraction disappearing, all at once, over something small.
What Is Going On in Your Head
Research on the ick is still young, but a few explanations hold up.
Disgust is fast and protective
Disgust evolved to keep us away from things that might harm us, like spoiled food or illness. It works fast and without reasoning. Psychologists have argued that the same system can attach itself to people, especially in early dating when we are evaluating someone quickly and with incomplete information. A behavior that reads as clumsy, childish or unhygienic can trigger a small disgust response even when there is no real threat.
The idealized image cracks
Early attraction is partly built on imagination. You know only a sliver of the person, so your mind fills in the rest, usually generously. An ick often happens when real behavior collides with that idealized picture. The flailing run is not bad, it just does not match the smooth, composed person you were imagining.
Some people are more prone to it
Early survey research on the ick, published in 2024 and based on several hundred adults, found that most had experienced one. Women reported icks more often than men, and people who scored higher in disgust sensitivity and in perfectionism about choosing a partner were more likely to get them. In other words, icks say something about the person feeling them, not only about the person triggering them.
Anxiety can disguise itself as an ick
For some people, icks appear right as things start getting serious. If you notice you consistently go off people at the point where they show real interest, it is worth asking whether the ick is about them, or about closeness itself. This pattern overlaps with what attachment research describes as avoidant tendencies, which we covered in attachment styles explained.
Trivial Icks Versus Meaningful Ones
The most useful thing you can do with an ick is sort it. Not all icks are created equal.
| Trivial icks (usually fade) | Meaningful icks (worth listening to) |
|---|---|
| How they run, dance or sneeze | How they speak to waiters or staff |
| A slightly cringe joke | Jokes that consistently put others down |
| An unusual outfit choice | Ignoring something you clearly said no to |
| How they eat a particular food | Lying about small things, repeatedly |
| Being nervous or awkward on a first date | Being dismissive when you share something personal |
| Baby voice with their pet | Getting angry when they lose a game or argument |
The left column is about quirks. Everyone has them, and once you know someone better they tend to fade into the background or even become endearing. The right column is about values and behavior. Your gut may be reacting to a pattern before your conscious mind has caught up.
A simple test: if you described the ick to a friend you trust, would they laugh, or would they frown? Laughter usually means trivial. A frown means pay attention.
What to Do With an Ick
Give trivial ones a little time
If the ick is about a harmless quirk and you liked the person a lot before it, see them again. Many people report that a trivial ick disappears after a few more dates, once the person feels three dimensional rather than an image. If it is still there after three or four meetings, that is information too.
Look at the timing
Notice when the ick showed up. If it hit the moment they texted to say they really like you, or right after a great night together, ask whether it is about them or about getting closer. That pattern repeating across several people is worth reflecting on, possibly with a therapist.
Do not use it as a running joke about a partner
In a longer relationship, sharing a list of icks about your partner with friends erodes respect over time. John Gottman's long-running research on couples found that contempt, meaning eye-rolling, mockery and disgust, was one of the strongest predictors of breakups. A private ick is normal. Turning it into a public bit is a different thing. If you notice contempt creeping into how you talk about a partner, the post on how to stop fighting in a relationship covers what the research suggests.
Take meaningful icks seriously
If the ick is about how someone treats people, how they handle a no, or whether they tell the truth, you do not need a better reason to step back. The post on relationship red flags that matter goes into which behaviors are worth acting on and which are not.
Can the Ick Come Back After It Fades?
Sometimes. Stress, a bad patch, or simply getting used to someone can make old icks louder. In a stable relationship that is usually a sign of something else going on, like resentment or fatigue, rather than a sudden discovery about your partner. It is more useful to talk about what has changed between you than to focus on the specific behavior.
A Lighter Way to Think About Compatibility
The ick is a reminder that attraction is not just about checking boxes. You can match on paper and still feel nothing, or have a silly ick about someone who is genuinely good for you. Compatibility quizzes are fun precisely because they make you think about what you value, even if no test can predict how you will feel about someone in person. We looked at what the research says about that in do love compatibility tests actually work.
If you want something playful to try with a date or a friend, Matcha AI offers quick love tests and compatibility quizzes. Treat the result as a conversation starter, not a verdict. A quiz cannot tell you whether an ick will fade. Spending time with the person can.
