underage sex

the best thing in the world, probably before porn(for most people)
and a great way to waste time with your 'significant other'.
both participants must be under 18 or so of age.(depends on where you live)

two 15 year olds. fucking in the school toilet like rabbits in between classes then skiving off classes just to screw each other. THAT, my friend, is totally underage sex.

undercleavage

Cleavage that can be seen from beneath a woman's top (or the strip of fabric that passes for it).

Undercleavage is nice and all, but you almost have to wonder how her boobs don't slip out of her top...

Undercover Slut

A girl who one would not assume gets with a lot of guys (whether because she is weird, nerdy, or just really nice) but in reality has hooked-up with half the school.

Bob: That Mindy girl's pretty cute, she seems really smart though. I wonder if she'd get with you.

Joe: Dude, she's an undercover slut. She gets with everyone!

undercore

The musical genre practiced by the band Deadsy. Elijah describes the band's low and dissonant style as Undercore. Elijah's low baritone singing style, down-tuned guitars, Dr. Nner's synths and Carlton's Z-tar give the music an almost surreal quality. Deadsy's sound is often compared to Gary Numan. Undercore is often described as having elements of Industrial, Goth Rock, New Wave, Death Metal, Post Punk, and Synth Pop.

"We wanted to make something that was transcendental, really rule-defying, and very against the grain. And when people listened to it at first, it would just feel very like a sense of foreignness, almost like watching a David Lynch film." - Elijah Blue

"The sound cannot be held in comparison to any band past or present. The sound is UNDERCORE. Something pure that cannot be duplicated."

undercover fat

Someone who doesn't look fat while clothed, but secretly hides a gut

I had a locker next to that kid in gym class in high school, and trust me, he's undercover fat.

She looks hot at first, but she's just an undercover fat girl hiding beneath that sweatshirt

Undercover Nigger Lover

A white person who has sex with black people, but finds it shameful to tell their white friends for fear of rejection or ridicule.

Tim's dad kicked him out of the house & disowned him when he found out Tim was banging black girls. He tried to hide it by being an undercover nigger lover, but all UNL's eventually get caught.
