The infamous Gro-Hawk, which is actually is the shortened version of "Gross Mohawk". It occurs when (typically) a boy who has an even cut, grows tired of it, and then styles it as a Mohawk, (spiked up hair in the middle area).
Dan thought the ladies liked versatility, so he made a Gro-Hawk out of his even-cut hair. He does not know why all the girls laughed uncontrollably whenever they passed him.
Guy 1:(to himself) Man, I've worn the same hairstyle since I was in 6th grade... I need something new. *grabs hair gel from his grandfather's house and smears it onto his hair, styling it like a Mohawk, but leaving it to the normal shag on the sides* Oh yeah, they ladies gon like me now!

Friend: Dude!, What happened to your head, man?
Guy 1: It's a Mohawk, DUH!
Friend: More like a Gro-Hawk! *sighs while shaking head, walks away*
