Goober Knobber
Its when you look in the newspaper obituaries for a recently passed old woman. Then you and your friend dig her up from her grave. Guy 1 puts mouth on the old womans vagina while guy 2 jumps from the tombstone and lands on her stomach. Whatever lands in guy 1's mouth is a goober knobber
Your breath is terrible, that last old bitch gave you a stanky ass goober knobber.
