mack mode

A common driving position in which the driver reclines the driver's seat back so that the driver can barely see over the steering wheel or dashboard of his vehicle. This driving position can be accompanied with driving with a gangsta lean.

Police officer 1: "Did you see that guy?, he's driving in mack mode....lets go pull him over"

Police officer 2: "Yeah, he's also got the gangsta lean going on and probably ridin dirty"

mack 10

One who thinks they are "hot shit" or can "get it on" with the ladies. Unfortunately most always a Mack 10 is a blithering idiot who does little to actually succeed in doing either of these tasks. In general a mack 10 is usually acting the fool.

I saw Mack 10 at the bar last Thursday hitting it up with Julie. Unfortunately he was acting a foo and everyone laughed at his pathetic efforts to geta piece.

i.e. kristoff terrific
