the greatest drink ever made. has 14 different flavors, but I think original is the best. when i first tried it I thought it was nasty, but then I tried a few more sips and now I'm addicted.

1) A person with a massive ego who mistreats and then mocks the people around him. This insult originated in Southern California, but is not reserved for musicians.

2) A crack addict with an ego problem.
That guy is such a rock star; he broke up with his lover by late-night text and then called her a stalker when she called him the next day.

That lady is a total rock star; she thinks she's a celebrity because she works at the food buffet at a 5 star hotel.

Every crack addict is a rock star.
