GG is two letters, and almost everyone knows its a sign of respect and friendship. If you can't type two letters, it's just BS. Hell, for me it's just reflex, sometimes I'm at the verge of throwing my fucking computer on the freeway yet I still say 'GG'. It's like taking your at off in a funeral; shows respect in the simplest of manners. It takes less than 2 seconds to tape the G button twice. If you can't do that, you're considered an asshole to the Toribash community :/
