Dirty Pig Bottom
Is a Gay Man who will allow any and all comers. He is a dirty because he will take anything inside him either a fist or man or ice cube tray etc...he is a pig because he does not care what man enters him without protection or what disease he might have. Ushually the pig is the one who has the HIV or other s.t.d. last he is a bottom because he likes to receive catch or be dominated.
I met this guy the other night in a bush at the Fenway in Boston. He was a dirty pig bottom, he let me go bareback and I brought a nerf water gun and we got into water sports, he let me assault every hole. Dirty little pig bottom he was, he is at my house now lol.
