Used in conjunction with Killzone (the first) and possibly Killzone 2 (if it, too, sucks).
Combination of the derogatory slang "Queer" and suck-filled, failure of a PS2 game, "Killzone".
"Son, where's your brother gone to?"
"Oh, he's just playing queerzone."
"DAMN! Killzone? That game will make Queers of us all! More like Queerzone!"
