look up any word, like donkey punch:
 
1.
Frat guy who is a friend with benefits. No strings attached with this guy- he is a slampiece but is an upgrade over the typical guy. Dresses nicely, never wears cargo shorts or socks with Sperrys, and likes to get with hot sorority girls. He has standards and so do you.
He's not a boyfriend, so he's not your frat daddy. He's not sloppy or embarassing, so he's not a booty call. He's a step above but he's not hubby material. This boy is just for fun.
I was up all night hooking up with my Sigma Chi fratslam.

the opposite of a slam piece. the female version of a slam piece. a guy that you are not particulary attached to but enjoy having sex with.
