Bloomington Party Pooper

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 Bloomington Party Pooper. Yeah... It was me.
