The Underachievers 

A rap group from BROOKLYN (Flatbush) that makes the absolute dopest shit. It's a duo, Issa Dash and AK. Their lyrics are insightful and smart, yet hard as fuck. Their most famous song is Herb Shuttles. The video for it is on youtube , lots of people turning up, bad bitches, and pounds of the dankest weed you'll ever see.

On a side note, they are part of the "Beast Coast" movement including Pro Era and Flatbush Zombies, and countless other new groups.

I just listened to Herb Shuttles by The Underachievers , and got stoned through the speakers.

The Undertaker 

When you throw your partner off Hell in a Cell, and they plummet 16 feet through an announcer's table.

"Is she okay?"

Undercover hot 

a person who does not demonstrate obvious qualities of hotness but is actually very hot once you look for more than one minute. These people generally have good personalities because they are unaware of their blazing hotness, but rather believe themselves average.

dude, that guy at the crepe place was so undercover hot. I didn't know to eye fuck him until he gave us our crepes. I need to go back and give him my number.
