 nub, nubbin, nubs. And when I joined the Navy and got stationed on my first submarine, I was going down the ladder, and the topside watch looked at me and said, get hot, nub. And I'm like, why would he call me nub? I asked him, it's like, did my grandfather call the boat? And he's like, why would you ask me that? I'm like, well, because only my grandfather calls me nub. And he started to laugh, and he's just like, well, that's a Navy acronym for non-usable body.
