Top Definition
Vassa is a crystalline alkaloid that is obtained from the leaves of the coca plant. When consumed, it is a highly addictive drug that is a stimulant of the central nervous system. It is also known to cause long-windedness, an inflated sense of self-worth, and the inexplicable glottal uttering of phrases like: "EH!"
Dude, let's blow this pop-stand - I've got a half a salt-shaker of Vassa at the crib.
