According to Wikipedia, "kuzbu" is "an Akkadian word which means 'seductive allure' or 'sexual appeal.'" Or, in the vernacular, "hotness." As in, "Whoa, his entire body is adorned with kuzbu." (That's what Shamhat said about Gilgamesh, according to that Wikipedia article.)
I'm hoping we can revive the word. Like: "Yow, check out that dude's fine kuzbu." Or "Hey, babe, you've got major kuzbu." I think it could be expanded into adjective form, too: "You look totally kuzbu in that dress."
