A person so fabulously awesome that traditional terminology does not begin to express their coolness. At once a rockstar, fantastic and capable of giving orgasms at a distance.
Also an alcoholic drink popular among vodka lovers. Made as follows: Drink one 12oz Minute Maid apple cranberry raspberry juice down to around the top of the label, add 1-2 shots of Smirnoff vodka, fill to lid with Rockstar energy drink. Shake and serve. Created by my boyfriend for yours truly who is a vodka lush!
Tad is such a rocktasm that the girls are crawling all over him, much to my annoyance.

That rocktasm was stronger than it tasted!
