Someone who cheats while playing "Guitar Hero" by placing a rubber band around the green button, limiting the number of buttons one needs to press, in order to obtain a higher score on the Hard or Expert difficulties.
"Dude! Did you hear that John got 100% on "Through The Fire and Flames???"
"Whatever. I heard he was green thumbing. I'd have to see it to believe it."
When someone that you don't want to talk to calls you and you ignore it, thusly pwning them via telephone.
"Dude, is that Mark calling again? WTF!"
*ignore call*
"Ha! Tele-pwned!"
