It was a Coke commercial with a faux-gangsta wigga kid showing us around his "pad" (which was actually his parents' house). He shows us his "lab" (his bedroom) and his little dog ("He nasty!") and his wheels (his parent's sedan). It ends with his mom yelling at him to take out the garbage.
He called himself something like dunno_247 and was a bit of an internet phenomenon for a while.
Anyone who can remember his name gets my undying love! Hyooooge bonus points for a link to the ad.
