Leftover Vanity Plates Of The Month

On a Lexus (the car that most commonly has vanity plates, far as I can tell):  CM YANKS.  Yanks I get, but CM?  Is it commies versus Yanks?  Or is he yanking something measured in centimeters?

NSNIPER.  What is this guy sniping at?

LADIGIT.  Any particular digit you're proud of?

YO[heart symbol]TQLA.  The back of a car is the last place you should brag about how much you love alcohol.
