Udo

A diminutive, camouflage-clad, mirrored-sunglasses-wearing, screeching and screaming, grunting and growling, moaning and groaning, militant homosexual lead singer of a German heavy metal band who looks kind of like a pig.

Hey, let’s hear an Udo version of The Star Spangled Banner, that’ll really go over with the NFL crowd.

Qusay and Uday

A pair of bullet-riddled corpses.

If I were one of the soldiers who stormed Uday and Qusay's shack, I would empty my clips at them, reload, then fire again at their dead asses.
