SMACK it

First invented (allegedly) by Dan Mace. Means let's get things done. A whole episode of 368 by Casey Neistat is titled after this phrase "SMACK IT."

For example, let's just smack it on the plane, meaning let's get it done when on the plane.

Smack Smack

1) The sound a thumper makes when it busts off

2) A common adlib used by certain rappers from North Oakland (Lil Rue, HD, etc..)

"Every day it's like I got some new niggas to kill (SMACK SMACK)" - HD on Minister Of Defense / Extortion Muzik 2

The more updates name for "sandles" or " flip-flop".
Derrived from the sound the "shoe" makes when hitting your foot.

Heroin. Most frequently used in the 60s.

When the smack begins to flow, I really don't care anymore...
