Meet an attractive lady at a party. Take her to a private area. Fuck her in the ass hoping that some shit comes out on your dick. Wipe shit off cock with either hand. Then on the way back to the party gently stroke the back of her head depositing her own shit in her hair. Hope everyone sees this and she starts running away crying.
Hey Dan did you see that girl with shit in her hair at the party?? Some genius must have given her the old BloomingtonParty Pooper. Yeah... It was me.
1: My mom made me study extra last night. Shes such a party pooper
2: Oh my gosh, you're the girl who got drunk and high at the party last night and crapped herself. Everybody knows you as 'the party pooper'
somebody who doesn’t like to have fun and is overall the lamest person you will ever meet. someone who has the name of “joaquin” will most likely be a party pooper
