After a serious fuck session when your partner is passed out on the bed face down, open palm slap their ass as hard as possible. Go retreive a marker and by the time you get back there should be a raised red handprint on their ass cheek. Use the marker to draw a turkey on the handprint like they taught you in school.
"Damn man what happened to you and that chick last night."
"Oh we were fucking and she passed out so I gave her an angry turkey then played COD"
