A sexy ass girl with large breasts that's very nice and outgoing! and all the guys want her so you're lucky if ya got this girl. If ya got her, better not break up with her it will be the biggest mistake of your life. McKenzies are genuinely nice but if you piss them off, they'll show how much of a bitch they can be. Usually they have brown hair, brown eyes and are white. CAN'T EMPHASIZE HOW SEXY THEY ARE ! Often is very humble about their appearance and don't think they're that sexy
Dude do you see that girl over there?
