*The codename for the atomic bomb that was dropped on Hiroshima on August 6th, 1945.

*The man of a character in MGS2; he's basically a fat-ass albino in a thick, highly-advanced EOD (Explosive Ordnance Disposal) BDU (Battle Dress Uniform), and is armed with an infinite quantity of C4's and a Glock 18. He looks and sounds like he could be a mafioso criminal or something......given his weight, he'd be more like a crimelord.
