Dave: You've just been standing around thumbing your nuts, haven't you?

green thumbing 

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."

Thumbie

An Indian that lives in Chatsworth, Merebank or Phoenix part of Durban, South Africa. A Thumbie has a fake gold tooth, talks in a bad Indian accent, too much gel in their hair, has a skin complexion that is darker than midnight, goes to the beach and swims with boxer shorts, uses a lot of slang, uses Vans, Life, Echo clothing/footwear. Thumbies are also sometimes seen carrying a face cloth. They listen to 2pac or slow R&B music, drive small cars as if they are ferrari's, fight with anyone who bumps them by mistake, think they the shit when they actually just shit.

Normal Indian guy: "Look at that guy with the gold tooth".
Me: "Yeah, he is definately a Thumbie".
