A country person with a fucked up grill/ teeth who can't find sex anywhere else but with his/her cousin and they make a bad habit of it to the point sometimes of having kids together.
To stretch the asshole of some unfortunate to such an extent by fucking it that it "gapes" open after retraction. To make someone your bitch by fucking them over.
Man, I got fucking gaped at the football tonight, we gotpumped. My asshole looks like a fucking blunderbus.
