A Younker is a sexual maneuver most commonly performed while rimming. The partner being rimmed farts in the rimmer's mouth and then proceeds to tongue kiss said partner with fart breath.
A complete and total dumbass. This person is so stupid every minute you spend with him is like being with krilin for 2 years in the hyperbolic time chamber. Brain damage is inevitable from hearing this man talk. He usually has a tiny penis.
