The ick
Etymology
The word "ick" for disgust is old, and the phrase "the ick" appeared as early as the TV show Ally McBeal (1999). The current dating sense was popularized by the UK reality series Love Island around 2017 and spread widely on TikTok in the early 2020s.
noun · /thuh IK/
A sudden, often irrational wave of repulsion toward someone you were attracted to, triggered by some small thing.
What it names
It names the moment attraction flips to aversion over a trivial cue — the way they run for a bus, a stray phrase, an odd laugh. What makes it useful is precisely its irrationality: the ick describes a gut verdict the person often can’t justify and can’t undo.
Example
I was really into him until he called the waiter "chief," and that was it — instant ick.
Related idea
Distinct from a red flag, which is a rational warning sign; the ick is a visceral turn-off, often over something objectively harmless.
