Buffalooooo....

... , He said, and looked at Her. She looked at him, and ignored him. That was after they cheered with beer. She took a sip and put down the glass. He was still saying Buffaloooo...oooo.... and kept staring at Her. Weird, She thought. But Buffalo was playing with Cleverland or someone, so She sort of ignored it. But... they all kept looking at Her... Awkward, She thought.
Well, it was His birthday party. He is from Her volleyball team. And He got 23 years old. So overall - lots of "young" people around. Then they (the people in the table) made Her to chug Her beer, using the left hand.

So - turns out - that there is this rule - Buffalo rule - that you can only use the left hand to handle alcohol and if you use the right one, and someone sees you doing it, then they call "buffalo" and you need to chug your beer (using the "correct" hand).
Different. So, better be ready for it :)
It could be a fraternity rule though, since all the boys in the crowd were from the fraternity. Who knows. But the night was interesting.
