munderwear

Underwear stained by menstrual blood, that has been deemed for use only during future "periods."

"Does anybody have some munderwear I can borrow -- I don't want to use an unstained pair of panties"

underwearhead

In a state of abject panic; acting out frantically and aimlessly. Derived from the image of someone running around waving their arms wildly, ricocheting off walls, and yelling gibberish at the top of their lungs, all while wearing underpants on their head.

"If space aliens ever invade, I just know I'll go totally underwearhead."

Underarm Armor

The little balls of deodorant that form under the armpit from applying too much or, for those who choose not to shave, from having too much pit hair.

Chris: Hey man what is this under my pit! I have lint.

Steve: Oh no dude that's underarm armor, you are now forever protected from the evil perspiration monster.

Undercards

A fangame that contains characters of Undertale and Deltarune. Some of them are fanmade. It is a card game made by a French person named Onutrem who plays Mario Kart and contains staff members.

Hey! Can you show me how to play the game Undercards?
Sure thing, but what is your card deck that you use?

Funderwear

Not your average everyday underwear. Mostly used for 'special occaisions' aka fun. Thongs, bikinis, lace, silk, etc.

I removed her undergarments with much force and ripped them and she fell over and I landed on top and we started watching Jay Leno on T.V.
