Nig Back

To recline a car seat back past 112.5°. The magnitude of the Nig factor is equal to (nig angle/360)2pi×Radius.

My head is touching the headliner. I have to Nig Back to a Nig factor of 5 to be comfortable.

back burned

when someone tries to burn you but their burn ends up being weak or false and you burn them worse based on their crappy burn.

Friend 1: "Dude your sister is such an idiot is dating that loser."

Friend 2: "Um, she dumped him...he's dating your sister."

Friend 3: "Oh! Back Burned!

back five

When someone offers up a high five and you give them the back of your hand instead of the palm. Could also be described as a "half a five."

A team scores and some dude says "high five man!" then as you are giving the high five turn your hand around to give the "back five." Maybe because you want to be cool with that person (not leave them hanging) but you're just not into it - it's like a weak high-five or a half-high-five.
