Someone who is
always the butt of the joke; usually among a well-intentioned
group of friends but sometimes passive aggressively aimed at a member of a group that isn't well liked.
Modern use related to older concepts such as scapegoat or whipping
boy.
"Dude, why are y'all so harsh on Trey all the
time?"
"Nah, man. We're all joking. He's just the
cheese bitch."
"Ugh, is Dillon gonna be there again? Fuck that
cheese bitch, you'd think he'd get the message."
