Lousiana Purchase 

When a girl's ass transforms into a large mass and volume within a very short period of time less than 12 months similar to the immediate U.S. land expanison of 1803.

Dan: Dude, I don't know how her ass got that big. It was small last year.

David: Yeah, it was, that's a total Lousiana Purchase.

A girl is giving head to a guy, but a third party is moving her head up and down.

No Purchase Necessary 

1)A common phrase in the advertising world - which gives rise to interesting loopholes - which tends to mean that you need not make a purchase to be counted as a contestant in an event.

2)Also, generally is a lie and means if you don't purchase but wanter to enter a contest, they'll send you a form to make you "feel" like a contestant.

The Sprite "under the cap" game said "no purchase necessary" right on the bottle, so Justin and David opened up all the bottles in the store and kept only the winners.

Gadsden Purchase 

The single greatest and most significant event ever to take place in American History. Covered extensively in APUSH, it was the purchase of what is now Southwestern New Mexico and Southern Arizona from Mexico. It was officially ratified in 1854. The treaty was negotiated by James Gadsden, who wanted to build a transcontinental railroad through the area. This railroad was never actually built, but the territory acquired through the Gadsden Purchase remains undoubtedly one of the most critical additions to the United States.

"You've got to be able to laugh at the Gadsden Purchase, it's what life's all about!"

"Who's your favorite president?"
"Franklin Pierce, obviously, because he ratified the Gadsden Purchase."

"It's June 8th, why are you having a party?"
"To celebrate the final approval and ratification of the Gadsden Purchase, of course!"

penis purchase 

Something you only buy into whilst wielding a raging stiffy. Examples include porno subscriptions, video games with hot girls on the cover, marriage, etc.

Usually I don't bother with paid porn but the genitals were hidden behind a paywall and I had to figure out if it was a man or a woman. That was a penis purchase I still regret.

Mule for Purchase 

1- Any mule that is available to be bought, as opposed to rented;
2- Any person taking a severe beating, albeit not so severe as the ones experienced by a rented mule.

I will beat you like a rented mule, or a Mule for Purchase. Fact is, if there is livestock involved, I will beat you like it.
