unleashing the Cheeks 

An unspeakable act of raw power and primative force, in which, an individual plows the nearest warm wet hole with reckless abandon and no regard for the safety of his partner. Punishable by death in most eastern block countries.

Cheekzilla gave his lady brain damage from unleashing the cheeks on her and knocking her head against the head board ALL NIGHT LONG.

unbearingly 

Unbearingly is sometimes labelled simply as being an incorrect word, and that the correct word for it is "unbearably." However, in slang, these two words mean different things. Unbearingly means to not be able to stand something to the extent that it is "breaking your back," or troubling you severely, and so you want it to go away (or desire to get away from it).

Here is an example of the difference between "unbearably" (which is a real word) and unbearingly (which is slang and not accepted in formal writing):
"That person was unbearingly nice" means that they were so nice it was unpleasant, perhaps annoying, or in some fashion distasteful. You didn't like it and were happy to get away from them. However, "That person was unbearably nice" means the opposite: the person was so nice, you could not resist them; you couldn't resist falling for their charms, essentially, and will likely look forward to seeing them again.
Of course, slang and "incorrect" terms differ by region, and in some places these two might mean the same thing, but where I live they do not.

unending

1) The name of the final episode of Stargate: SG1
2) An ending that leaves elements unresolved, allowing for sequels or just to shit people.
3) The usual way the second part of a trilogy ends, seeing as how most trilogies are not planned as trilogies, but seeing as how well the first did, producers and other money grabbers decide adding two more movies, books, etc. So when the time comes for an ending to the second part (seeing as how most sequels are never as good as the original) they need to give you a reason to come back for the third part.

1) "man that last episode of SG1 rocked!, despite the fact that very little was resolved, aptly named though"
2) "that was such an unending! What about all those zombies? and how did they get there in the first place!?!?!"
3) Examples include: Matrix trilogy, Pirates of the Caribbean triolgy, Halo Triolgy, etc etc

unloading zone 

the part a female or male's body where they like semen most deposited

Straight version: Carmen's unloading zone was chewing gum, so her boyfriend had to find someplace else to splooge.

Gay version: Ted's unloading zone was consipated, so he went to the store to get some laxatives to clear that shit out.

uploading spree

When a person feels like they have not uploaded photos on an online website, or feels that other have many more photos than them, so they add pictures, but they add a GREAT amount of them.

Aaron felt sad because he only had 35 pictures on Facebook and Maria had 100, so he went on an uploading spree.
