Frat Rat

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?”
