The act of a male ejaculating inside an anus. The receiver of the ejaculate will relax the anal walls allowing an undetermined amount of semen and fecal matter to leak out, thus creating the stinky cream pie.
Kenny: Hey bro that dude broke up with me.
Richard: What happened man, you two seemed so happy?
Kenny: I gave him a stinky cream pie and it ruined his expensive bed sheets.
Richard: Wow, I can't believe he didn't appreciate the stinky cream pie, your mom loves them!
Sticky pie: a game where a group of women (at least 2) stand in a circle around a gusher placed on the floor in the middle. They then have a race to see who can cum on the gusher the fastest. The last person to cum on the gusher must eat it. Works best when participants are drunk and hungry
omg, sis, we played sticky pie last night and I won! I feel bad for Suzan, though. She lost. I think he's in therapy right now.
