zack is a guy who can make any girl fall for him within a single look. He has the height, the body, the hair, the eyes, and the ass of an amazing hockey player... dont be fooled, hockey players can move their hips. Besides all the postives, here comes the ugly truth... he will say anything to get you in bed, and as much as you'd want too.. dont! he'll screw you over, and never talk to you again
last night i met a zack and it was amazing, but now i wish id never met him!

Short for "exactly." Used mostly in text or other digital messaging media when you are in a hurry, or want to sound like a hip young person who knows what's up.
(sends friend a meme about how they only need a 398% on their final to pass a class)
Friend: "My microeconomics class!"
Me: "Zack!"

(gets in argument with friend that culminates in saying "We can agree to disagree")
Friend: *shrug emoji, eye roll emoji*
Me: "Zack."
