1) An Amazing brand of car. Simply the best the automotive industry has to offer.
2) Best man or woman. Someone you're jealous of cause they get more than you. As in, the opposite sex likes them more than you. This causes the lesser to slander the person and make up lies about them.
This person may or may not drive a BMW but one thing if for sure. They get more money than you and the opposite sex is usually more than willing to make sure they're taken care of.
Wow, is that your new BMW? That's killer.
I heard this BMW can't get rid of the unwanted members of the opposite sex chasing them.
That BMW's boyfriend/girlfriend gave them all that money? Holy shit, that's love.
