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.

The Backhill 

An apocalyptic waste ground near Buncrana, Co Donegal in Ireland (GMT -48 years). It is currently the epicentre for red neck culture in Western Europe and the custodian of the purest red neck DNA. 2nd level education, books, lawnmowers, paved driveways and contemporary music are all forbidden within its borders along with marriage for the over 25’s.

You’ll only get away with that sort of thing in the Backhill.

Backrolls 

A responds to an individual who says something shady. Typically used as a one word response. When spoken the individual pulls their chin back and raises their eyebrows and states very clearly, "backrolls". This saying became famous through RuPaul's Drag Race. In season 5 Alyssa Edwards went viral after her elimination, this was one of her most memorable moments on the show.

Guy: "Your hair is fucked up and you look a mess."
Drag Queen (pulling her chin back raises an eyebrow and says judgingly): "Backrolls."

flag your backfield 

When you stick your index finger in your partners butthole during intercourse while tucking your thumb and waving your remaining fingers.

I love to flag your backfield.

Backfill 

To skip ahead and come back later to pick up the pieces.

Person 1: "How's your assignment going?"
Person 2: "Good, I did the conclusion first and I'm going to backfill the rest later."

backflush 

The turds/toilet paper that always manage to scoot back into the toilet bowl at the end of a flush.

I had to flush the toilet 2 times at work today because of the damn backflush.

Backfield shrinkage 

(n) In law or other industries where time is entered by professionals for billing to clients, the process by which the time is "written down," by owners of the firm to reduce the compensation of the professionals entering the time.

Frequently, this phenomenon is accompanied by the owners of the firm "writing up" their own time on the same file to increase their own share of the billings to the client.

I billed 200 hours last month, but the backfield shrinkage will probably cut that in half by the time that it gets billed out.
