A douchebag who spends upwards of 20 dollars getting his hair cut. The haircut is not a glam metal kind of style, but more of a contrived "messy" and extremely lame kind of style.
"Hey, how much do you think that Goo Goo Dolls assclown spends on his hair?"
"I dunno, but what a salon boy."
"Hey look, a salon boy!"
"Yeah, let's beat the everloving crap out of him!"
"Hey look, another salon boy!"
"Yeah, let's beat him to death in the road in front of his mom and then blind her!"
