A term used by US Navy personnel most often in the form of the acronym "nub" to describe new personnel aboard a submarine who have not yet qualified for submarines. Typically useless for anything other than cleaning, taking out the trash, and making fun of on watch.
Term is often mistaken by nubs to be synonymous with noob.

A lighthearted reaction upon receiving disappointing news of some sort. Usually something that isn't a particularly a big deal, esp. when it primarily affects someone else - sort of a mild schadenfreude.
