Synonym for cool

To inject an illicit substance (heroin, et. al.) directly under the skin rather than in the muscle, or the preferred way, in the vein. The result is typically, a small bump. This is typically done because your needle is crappy or your veins are shot. Shooting in the muscle typically hurts, so bumping isn't a bad way to go, and it beats snorting, arms down.

accidentally texting random jibberish with your ass.

n. A single hit of crack cocaine smoke.

Substitution for the "f" word.
