Ur uncle bisexual

Worse than ur mom gay, ur dad lesbian and ur granny tranny combined. When used in a back-and-forth of "ur mom gay" and "no u" -type arguments, it is the ultimate combo-breaker of all combo-breakers. When first stated, it will leave your opponent so shocked and surprised that they will be unable to comprehend your sheer awesomeness as they are suddenly launched into space. Asteroids collide at the mere whisper of this career-ending insult.
