ok
first off, you should of got up close to him and looked him straight in the eyes and stared into his soul, pushed him back showing him that you're a true threat to his masculinity. He will then most likely (try to) push you back harder to assert his dominance over you, but keep your balance and if you're heavy enough, try to stand your ground, if you're too light then dodge it. After this insult his snake size and this will make him go into a blind rage, pull out your handy pocket-knife and rip his pants off and cut his wee-wee off so you can assert your dominance as the alpha-male of the room, after this spit on him and in the process this will take all pride that was left. His friends will now follow you as pack-leader and your girlfriend will totally want you to bang her afterwards.
you did everything wrong you could've become a king
