1. A greek system leech. Someone male (could be female) who is not an actual member of a particular Frat, but comes to every Fratty Function anyways. Most often these people wouldn't be accepted by the frat anyways and no one really wants them around.
FrattyFrat #1: So you think John's showing up tonight?
FrattyFrat #2: Dude, when doesn't that Frat Rat show up?
FrattyFrat #1: Shit... oh well, lets go rape some high school girls.

Just your typical cock sucker frat bro. Buddy loves his blow and his white claws. He spends his week days smoking the worst skunk weed you’ll ever find and the weekend fucking 3’s and telling his friends he’s “that guy”

A girl who goes around to every frat house not only sucking but swallowing the semen from every male in site. This girl doesn’t even need her kitty played with to have fun as she enjoys viciously sucking the soul out of every person with a penile.
“Hey John did you see that girl kaitlyn sucked off 66 guys this semester?”
John: “Yeah man isn’t she a frat rat?”
John: “Yeah man isn’t she a frat rat?”

A putrid, dirty home wrecking whore that slithers their way into frat houses and fucks every dude in a five mile vicinity with no protection regardless if they have girlfriends or not.
Frat Boy 1: Do you know Grace?
Frat Boy 2: Oh, that Frat Rat? She's fucked & sucked every dude in the house, even the ones with girlfriends. She even ruined her boyfriend's previous relationship just to cheat again!
Frat Boy 1: Dirty Frat Rats.
