Zack

An argumentative prick who always thinks he's right even when he's wrong. Does not hold the record for most deliveries at Wings Over Happy Valley. Incapable of performing that thing on the bar that alpha males and alex can. Also believes his stock ass car is better than a mazda 3. yeah right! that thing took 124 deliveries in one day.

Stop being a zack, texas roadhouse sucks.

An Uncle Zack will usually enter the bathroom, be silent, and usually look in the mirror for extended periods. Be careful not to get caught peeking to see if the Uncle Zack has left.

I was done pinching my loaf but couldn't wipe because there was an Uncle Zack in the bathroom.
