Blumper Decker

The combination of a blumpkin and an upper decker.
To defecate in the tank of one's toilet while receiving a blowjob.
i.e. To get mad domepiece while releasing the beast into the top of that Faggoty Ann's toilet.

Leopold: My asshole roommate fucked my mom last week, so I asked his mom to come over to 'see which of his clothes not to donate'.

Lance: My stars, good play.
