The asshole version of Zac. Somehow the loss of the K in his name caused mental retardation, almost like a missing chromosome.

Is the type to wave his limp dick around because he is a fag who can't get it up. Also inclined to get drunk quite frequently and will act like a controlling asshole when drunk.
Will take it too far when trying to get a girl, because it has been so long since he's gotten any. Often will invade space by groping women that are most definitely not interested and taken.
Also beware, you may want to actually like a Zac. They will draw you in thinking that they are a decent guy. Until the millionth time they eat all of your food or break promises and talk shit.
Geez, is that guy a Zac? He just let himself into our house and stared eating our peanut butter out of the jar.

An extremely HOT heartbreaker who will only leave you alone wanting to die. NEVER trust a Zac. Because no one will suspect it coming.
Wow... I can't believe it. I actually thought Zac loved me... Boy, I was wrong.

The Zone Address Code, or ZAC, is a clarifier for a particular suffix of a street name in a given address.
Street, Drive, Boulevard, Avenue, Circle...

Usually gay, smart in school, but stupid on the streets, friends with the most amazing people. As for looks, blue eyes and brown hair. But small penis.
"damn, if it weren't for Zac's amazing friends, i think i'd beat him up."

a fat man that spends spare time taking pictures of buses and hanging out with gay men.
Guy 1 : Hey, see that fat guy taking pictures of buses with gay men?

Guy 2 : Yeah?

Guy 1 : He must be a Zac.

Guy 2 : You are totally right.

A retarded ass, dumbfuck who thanx he is the shit, with a jew nose and greasy mushroom cut. He thanks he can go back to any girl and cares more about snowboarding then ANY of them. He has the worst ass lines and cant even cum up with any NEW ones. He is secretly in love with his best friend and they ass hump when they go up to his cabin. He ignores people once he thanks he has them even though they wont stick around forever. He is the most uncomfertable person to be around and ui thank he acctually thanks that people care about what he is saying when all he talks about is how he hurts himself so much. AND nobidy cares about all his sports. Its not like hes any good at them. so he should go fuck himself :)
