The action or process of having a crush on someone again after getting over them the first time. It can happen days or years after the initial crush.
It is not considered a recrush if the person has had a continual crush for the duration of time, there must be evidence of uncrushing.
"Shoot, I was totally over him and then he called me last night I totally recrushed."
Girl 1: "Why do you keep talking about Vince, I thought you were over him?"
Girl 2: "Something changed when he wore that Cosby sweater the other day and now he's my recrush."
