Rusty Bumper

When the drunk redman man (generally named Tanto) tries to slip his third mocassin into your turd cutter and ends up just dick punching your fart box. It is called the rusty bumper due to the uniquely rusty color that a redman's dong exhibits.

God damn Tanto was so drunk last night he kept giving me the rusty bumper.

When you're having sex, you shit in your hand and smear it across the buttocks of your partner, and proceed to hump aggressively.

David pulled a fucking rusty bumper on Max, and he didn't even see it coming!
