After giving a girl a cream-pie she stands above your head, then sitting down somewhat forcefully on your mouth she yells, "Patty Mayonaise!"
Friend:"Ha dude nice fat lip how did that happen?"
Me: "Well my girlfriend gave me a Patty Mayonaise last night. It was so worth it."

Last night I was screwing my girlfriend then I pulled out and shot her in the face with the mayonaise pistol.
