underbreastimate

the act of underestimating the size of your boobs when trying on clothes

Girl: "I saw this really cute shirt and it looked like it would fit perfectly, but my boobs were practically popping out. I underbreastimated big-time"

Underbender

While standing behind an unsuspecting fella, who is preferably deep in conversation or thought, one would reach a hand through his legs upward, grabbing the top of the belt buckle and in one swift, smooth and forceful motion pull down and back and watch the poor gent either smash their face in the ground or complete a front flip. Be prepared to run.

Geoffrey had been egotistically running his mouth all day, so when I noticed he was taking a few pictures with his haggard harem, I swooped in and administered an unforgettable underbender, on film.

active undercarriage rust protection

Marketing-speak for a chronic oil leak on your automobile - generally one that takes more effort to fix than the car is worth. Comes standard on most General Motors products since the early 60s, as well as Saab 900 series.

Click: Dude have you seen that grease spot on your inner fender?
Clack: Oh don't worry about it, that's just active undercarriage rust protection. Paid extra for it. I think.

Very simple. This is your pet's fucking stomach.

Kitty loves it when you scratch her undercarriage.

Underbelly

The "second stomach" of fat people that hangs below the normal waistline, usually appears when obese women try and hide their huge gut by pulling up their pants.

That fatty had a huge underbelly, she looked like Jabba's dancer from star wars!

Underwear

The undergarments a guy wears just about anytime other then when hes knows hes about to score. They are barely holding on to life and could only be identified as underwear by either the owner or a person with a creative mind. Unlike famine underwear, men will wear this for an indefinite period of time until said garment vaporizes.

Just put on my favorite pair of underwear and it disintegrated
