The double faced tummy wag 

an act of excitement or celebration;

When two men stand face to face, drop their pants and underwear, put hands on hips and "wag" side to side. This allows their penises to "wag" like a dogs tail simultaneously. The act may be escalated by standing close enough for the penises to hit one another to simulate applause.

Tim and John had just beaten Frank and Joe in the last match of tennis, and really rubbed it in when they gave a standing ovation via, the double faced tummy wag.

The Double Turkey 

A variant of the Turkey handshake fail, where confusion between whether a handshake or a fist bump will be played leads to an accidental fist-palm. This new handshake takes that idea and doubles it, and makes it intentional. The first individual holds out a fist, the second person open palm slaps the fist in a downward fashion; the second person then makes a fist, and the first individual slaps the fist in a downward fashion.

John showed us that it was possible to recover from the fatal Turkey Shake by doubling down with the Double Turkey.

reverse double eviction 

This obscure reference refers to the eating of (at least) two corndogs in one sitting. The etymology breakdown is somewhat apocryphal, but essentially is from the latin 'evictus', which has one of the meanings of 'overcome and expel'. Corndogs, by their very nature are non-trivial to process both culinarily and digestively. Shut up Jim! It's not funny!

From www.etymonline.com
evict (v.)

mid-15c., "recover (property) by judicial means," from Latin evictus, past participle of evincere "overcome and expel, conquer, subdue, vanquish; prevail over; supplant," from assimilated form of ex- "out," or perhaps here merely intensive (see ex-) + vincere "conquer" (see victor). Sense of "expel by legal process" first recorded in English 1530s, from a post-classical sense of the Latin word. Related: Evicted; evicting. Compare evince.

Hey Nic, what's for lunch?

the double bust

When you're fucking a dumb white girl, that's pretty hot and wears uggs, and you rip off the condom at the last second and bust in her anyways. You didn't want to, but you did it anyways, so you put on some sweats and a tshirt and walk out to go get Mcdonalds.
