Stupid Dumb Nigga, a nigga that just don't know when to stop playing the fool. Usually wants to be a know-it-all or smart-ass, but is clearly missing 3/4 of his teeth. Demands quite a lot of attention and is especially loud when doing any thing in particular.
"Dude, what the fuck is up with these SDNs?! These man don't know when to stop being retarded!"
