Party Girl: Why is the bathroom door knob in the sink and Jasen in the tub face down with Nazi symbols and penises all over his asian body?
Party Boy: After speaking only spanish for 20 minutes he locked himself in the bathroom. So we broke in to make sure he was ok. He was sleeping on the toilet, But for making us worry we tub-nazi-penis trifecta'd him. He's our Designated Blackout (DB).
