Perpendiculate 

The act of becoming perpendicular to something, usually the floor.

My alarm kept going off this morning but I just couldn't gather enough energy to perpendiculate myself.

Its the pneumonoultramicroscopicsilicovolcanoconiosic fusion in bisectors of the photosynthesising ethis of circumlocution in floccinaucinihilipilification of pseudoephedrine in the common equilibrium in the crystalation process in the perpendicular of covalent bonding contrasting the antidisestablishmentarianism theorem.

"I used the Perpendicularbisectedunicellularphotosynthesisingreproductiveasexualcollectiveconsciousness formula to discover the equilibrium of the bisector in the photosynthetic material."

poopy perpendicular 

An act of anal sex in which the penis is never actually inserted into the rectum, but rather the man fucks the woman's butt cheeks in a manner reminiscent of titty fucking.

My girl's got some small titties, so I pulled a poopy perpendicular on her last night!
