Marvel Jack

That knobhead who goes to the park with you and your mates, yells wogwan at every person there, then gives himself brain trauma with an inanimate object.

Person1: Did u hear about that fucking kid
Person2: The one who tried to look cool by running up a skateboard ramp then fucking smacking his head into it
Person1: Yeah lol, what a Marvel Jack. He can’t read or write anymore
