A fruit loop refers to a sexual act involving anal sex. The man who is giving the anal sex is supposed to punch the recipient in the back as he is about to pull out his penis. The punch is used to make the recpient tense up as you pull out so that their sphynkter comes out and they are not able to control their bowels. (the shpinkter looks like a purple fruit loop.)
