Popular exercise often performed by Frat Boys which involves standing in the squat rack for extended periods of time curling pitifully small weights. This activity pisses off serious weight lifters who want to use the squat rack for its intended purpose: squatting.
Last week there was this prettyboy doing frat-curls on my leg day, so I took him out back and shoved a barbell up his ass.

When you wake up in a frat house after a night of hard drinking and look in a mirror to find that your makeup is smeared, clothes nowhere to be found, and hair is in a curl that just won't come out you have a frat curl.
Rita your hair is in such a frat curl, please go shower!
