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.

"I gave my GF a sexy The Undertaker last night."
"Is she okay?"

Underfucked

sexually deprived

1. Yo look how hard she's hitting on him... she's definitely underfucked!

2. That guy is completely underfucked. He just desperately asked her out again after she told him to fuck off for the third time...

underfuckingstand

When you don't understand something and you are super pissed.
When you don't feel like saying "fucking understand"
When fucking understand just doesn't quite display the needed emotion.

"I don't underfuckingstand why your acting like this"
