When a female has a second bum

almost like a double chin

"does my underbum look big in this?"

"does this skirt emphasize my underbum?

"underbum is way rank"

underbrag

To say something that would be a brag isn't true.

Not to underbrag, but my penis isn't like a club.

Underbrella

A tactic by which a person stays dry during a rainy period by taking advantage of an above average height stranger holding umbrellas by walking underneath them.

A person may commonly use this in densely populated areas, in order to stay dry if they have not planned ahead for poor weather.

John: "Hey Peter, where's your umbrella? It's pouring outside and you're completely dry"
Peter: "Who needs an umbrella? I just underbrella-ed over here"

Underbritches

BIG, white, cotten briefs of some sort.

Had to pull up my underbritches because they were ridin' down my butt.
