Underhang 

i) The visible portion of a woman's vulva, from behind, when she bends over.

ii) The amount the vulva protrudes (sticks out) downwards when a woman bends over.

iii) Cameltoe, as seen from behind, when a woman bends over.

Women who have a plump vulva with fleshy labia have a lot of underhang, while women with a flat vulva and lean labia have very little underhang. All the above definitions apply to both clothed or nude women.

a) Wow, check out the underhang on that gymnist!

b) A girl with a nice ass but little underhang is like cookies without milk.

underlaid 

Having gone without sexual relations for an unreasonable amount of time; by extension, the feeling of being "horny".

"Dude, I am so underlaid, I can't even remember what a penis/vagina* looks like".

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.

undersharing 

The state when one feels less involved in posting stuff on social media than one desires to, frequency-wise or volume-wise, usually in order to overly express one's self or to fulfill a business need, thus experienced by extroverts and business people.

OMG I'm undersharing. I forgot to mention what I ate on Twitter.

underhanded comment 

A snide statement that is hidden behind what seems to be a polite one. It can be an inside joke, but can also have negative connotation.

Chris Brown: “I f--- with Frank Ocean! Reminds me of a young James Fauntleroy or Kevin Cossum”

Frank Ocean: “i f---s wit chris brown, reminds me of a young sisqo or ike turner.”
“i just dont like underhanded comments. thats all im saying.”
