Get the ur brother is ur mothermug. One of the eight most deadly phrases in the world. It has not been muttered since the anciet great wars, not to be used lightly.
Justin: Ur mom gay
Kyle: Ur sister a mister
Justin: That's it... Ur brother is ur mother
All the stars' gravity becomes 10000000000x stronger pulling everything into their reaches. Once the final star has been born the big bang happens again.
