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 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.

lad in the back

When you are a girl and always going to be in the friendzone because you are such good friends with the guys. It's as opposed to being a lady in the front, which everyone knows is the position where the girlfriend sits when the guy drives.

I'm always going to be a lad in the back, but never the lady in the front
