Underbeard

Facial hair that grows on the underside of the chin. This style of beard is frequently sported by the overweight, in which case it technically resides on their second chin.

"Kids, take a page from the Underbeard King and get rid of your neckal hair,
`cause you're lookin' like Chewbacca did a face-plant into Nair."

~ excerpt from the traditional Ballad Of The Underbeard

Underminer

A person that will intentionally sabotage someone else through any means necessary.

He stole from me after I tried to help him, so I undermined him by making sure every business in the area knows that he is a shoplifter.

I am an underminer.

undervite

the most minimal form of an invitation, but not quite reaching the level of an unvite. used to make an offer, while indicating that ones presence is not mutally desired. frequently used by a couple to a potential third wheel. commonly phrased by using "if you want."

me: kim and i are going to the bar around ten. you can come too, if you want.

you: dude, that was such an undervite.

underwire

A trashy tattoo that follows a woman's curves under her breasts, the way an underwire in a bra would. The 2000' tramp stamp.

When you meet a tatted chick with an underwire, you know she's easy!
