Frat Curl 

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.
