double-decker threesome

The most supreme of all sexual positions, includes two (2) midgets and a normal sized person. While the normal size person is making out with the midget, who happens to be sitting on the other midget's shoulders. The bottom midget simultaneously performs oral sex (blowjob) on the normal sized person, thus creating the double-decker threesome.

The double-decker threesome in the episode of Little People Big World last night, gave me a raging boner.

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!

upper decker

The act of removing the lid off the back part of a toilet and pooping in it. Poop comes in the bowl over time after flushes. Usually done at big parties that have gone wrong.

The host of that party was so horrible that Andre couldn't resist pulling an upper decker before we left.
