underwhere 

Extremely skimpy and revealing undergarments, usually women's, worn to divert attention from their faces while reducing waste of natural resources. Garments of similar minimalist design may be worn by men if they are gay or French.

For quick results Bill advises to check a woman for three things: underage, under the influence and underwhere.

underwhelmed

h'underware

H'underware (contraction for hair underware) is a very dense patch of pubic hair, usually on a woman, that extends from just below the navel to the upper thigh front and back and is typically the result of an extreme case of winter bush.

Oh man, she's really hot except she's sporting a massive pair of h'underware.

undershare

Providing too little information or context when blogging or tweeting. With the ubiquitous status updates on Facebook and Twitter, people forget that it can be helpful to provide enough context for a message to be meaningful. So, ironically, while people tend to overshare, they also undershare at the same time!

Guy 1: I got a tweet last night from Jim, he said, "this is so effing great!"
Girl 1: I saw that, too. Why does he constantly undershare?!
Guy 1: Probably wasn't that great.

Underware 

Computer software that is like a root kit, virtualizing the entire system. It is designed to intercept all input output. It is used for information control. Its existence is not formally acknowledged.

Changing my webcam resolution is not working- it must be the underware preventing the settings change.
