Rush Advice, I've kinda got a unique story...

[4est]

I need some advice about what to do here, I really want to join a certain fraternity here on campus because it seems to really fit my presonality type very well...
here's my problem, i recently went to a 'get together' at the house that one of my friends threw who was in the fraternity, he was the only one from the frat who was actually there for a while until one of his friends showed up much later... well i was drinking, as was everyone else, and long story short i made myself look like an ass in front of his friend from the fraternity, [not that i did anything physically but he was kidding around about a sesitive subject and i tryed to blow it off but ended up draggin it out] I know the converation we had will come up at rush because its a very 'interesting' subject...
what do i do? blow it off again and basically pretend it didn't happen or when they ask me about it try to explain it and justify it [again] or do i just not rush that fraternity?...
