backlip 

1. How lazy skaters say "backside lipslide". I am one of those skaters (thats right, i still live at home)

2. A Mythical beast, said to be one half dragon, one half barbera streisand and one half someone who's bad at math. It is rumoured that this beast caused the exctintion of the Dinosaurs.

1. "Jesus Crisps, homie-X jus threw down a sick backlip on that there 6 million stair rail!"

2. "OH MY GOD, RUN FOR YOUR LIVES! IT'S THE DREADED BACKLIP AND IT'S GOT A MICROPHONE!!!"

Backlit

Ejaculating an unfathomable amount of cum on a human males back, typically after engaging in homoerotic activities with a male (or trans male).
The word is stemmed from the phrase "light up my back."

"Dude, how was Thailand? Did you get any of their cheap sex massages?"
"Naw dude, I paid them extra to backlit me! It was awesome!"

Monkey Double Backflips 

Extravagant and exotic sex techniques used by females to lock down a high value male.

She was with Thomas but he was kind of boring. So she also met with Sebastian from sales department who was making six figures, has a sixpack and a nice car. So she does monkey double backflips all over him to get herself in a better financial position if she continues this until he takes her as a wife.

Double Boner Backflip

In an all-male threesome, two men lay on their backs with their penises touching to create a "Double Boner." The third male, standing on an elevated platform positioned above the other performers, proceeds to do a backflip off of the platform. At the end of the rotation, the diver will land with the two penises engorged in his rectum successfully completing the "Double Boner Backflip."

Man 1: "Hey man, how's Kappa Alpha pledgeship at the University of Tulsa going?"

Man 2: "Well it was kind of boring until they made us do Double Boner Backflips with each other."
