Blumper-Decker-Dactyl

The act of receiving a blumpkin while taking an upper decker as the female is also giving two guys on the sides handjobs (the head and hand movements mimic a pterodactyl flying.)

Dude, I felt like I was in the prehistoric era because of how believable her pterodactyl was when she was giving us a blumper-decker-dactyl!

Double Blumperdecker

When one person shits in the water tank, preferably onto the ballcock, while receiving oral sex from a partner who is sitting on the toilet, AC Slater style, also taking a shit.

So I went to leave an Upper Decker in Bill's toilet, but Mary came in and offered to give me a Double Blumperdecker since she had to shit, too.

Blumperdecker

Receiving a Blumpkin while taking an Upper-Decker, it's as simple as that.

Joanie loves Chachi so much that she gave him a Blumperdecker the other day in a rundown truck stop bathroom because they had nothing better to do.

Blumper

When a male is sitting on the toilet, taking a dump and a girl is giving a blowjob at the same time.

When trailer trash whores having nothing else better to do than having sex with their nephews

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'. I broke out a decadent white zinf at the end, and one thing led to another... Next thing I know I'm getting him back with a blumper decker in his bathroom with his mom.

Lance: My stars, good play.
