Sk8erboi 

A teenage male who is a wannabe "skater", although does not posses any skateboarding skills but dresses like a "skater" nonetheless. A "Poser Skater". Usually these males are between 11-15, after which they grow out of this phase. The telltale sign of a Sk8erBoi is that he is never actually skating on his board, but always carrying it with him.

Did you see John this month?
He's a Sk8erBoi now, he used to be an Emo, but that didn't work out for him.

A young teenage male WALKING down the street with his board tucked under his arm.

Avril Lavigne is a mainstream Sk8erGurl.

Posers. Boys who think they can skateboard and think they're punk. But they're just gay

Also the gay way to spell Skater Boy. Which is also gay!

Avril Lavigne is a poser, hence she uses the spelling sk8erboi....
