An overweight bitch who likes to party and get sloppy over all the dudes. Can be heard from 4-6 miles away, weather permitting.
1: Who the fuck is that fat drunk bitch?
2: She's one of the local party buffalos.
The ugly friend of that hot girl you are trying to hit on at the party. She inevitably cock blocks you.
What happened dude? I thought you were gonna get some.
Her party buffalo of a friend cut in.
