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.

unsprung 

An anal virgin. Someone who has not had significant anal penetration (beyond, for example, fingers) to stretch the "anal spring".

LISA: Of course Rick is going to want to put it in your butt, girl! The way you show off that booty, you know a man's going to show it some love.
KELLI: But I've never done that before. It's so nasty. Won't it hurt?
LISA: Awww, my unsprung hero. It's gonna hurt the first time, but get some lube and make him go slow. After that, you'll be okay. Just another sprung sister.

Unspiring

The opposite of inspiring.

That meeting with our boss about how 50% of us will probably lose our jobs was pretty unspiring!
