I like CRAMER's "AZZ MAN", but for me it would have to be "CAREFREE", or "RELAX" or "moveover" Or my favorite, "ROTFLMA" (Rolling On the Floor Laughing My Ass Off) I know, but someone might not know what it means.
Side note, I wanna get one of those LED read out that you can program from the cockpit and send people messages after i pass by. Like "About time grandma","jack ass"(for the slow people and truckers in the speed lane). Or if you see a hottie with a dude, you could say "Hey, I knew I recognized the back of her head".
