The Diddy Party is a commonly known party that homosexuals or opposite-gendered males attend to. It is where men have gay sex, such as oral, and anal.
P Diddy: "There ain't know partylike a Diddy Party"
John: "Damn, i didn't join, what went on there?"
P Diddy's friend: "nothing much my nigga just came back from the diddy party son, you should've been there. There was dick and balls everywhere, son, nah son you need to come the party next time, B. Nah, Diddy was shaking his ass, son, his balls were everywhere, there was hair all over the place. No Diddy though, B, word is bond."
