Piece of game
The homosexual male or female that a heterosexual person in prison takes on as a boyfriend or girlfriend of sorts. The piece of game (p.o.g.) performs sexual favors for the heterosexual, cooks for them, and does anything else the heterosexual wants all for the guise of being in a relationship with that person.
That's my piece of game right there.

You better leave him alone, thats MY P.O.G.!
