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.
