    Last year, I ran a Twitter Space titled “I interview people (you, maybe) about the ick”. I defined the ick as a sudden drop in regard or attraction based on something seemingly trivial the other person did. It might happen on a date, in the early stages of a relationship, or when your cute coworker does something at work Then I asked: What’s the first time you can remember getting the ick? When did you last get the ick? Do you know of a time someone found you icky? What’s the most memorable tweet you’ve seen about the ick? What ick tweets are memorable (according to various terminally online people, three quarters of them men)? I got the ick when I saw a guy running into a screen door I got the ick at the beach when I saw a man in the ocean getting knocked down by a wave …when I was feeling threatened by a guy in the subway and I saw another man who wasn’t helping me …when he took his wallet out of his pocket and a bunch of coins fell out …because he couldn’t find a parking space …when I saw that my wife had a ‘go bag’ and was prepared to leave me at any given moment …because he’s trying to change lanes and he can’t because the cars won’t give him a gap …because he kept rolling his dice off the table during a board game And what icks did my interviewees actually have? I interviewed 14 straight(-ish) men, 5 straight(-ish) women, and one gay guy.
