nuc
1. Nickname for a sailor trained to operate a Navy nuclear power plant. Navy nuclear power has zero tolerance for error, so nucs train day-in and day-out, and are constantly monitored. Hence, being a nuc is very arudous and stressful. Add this to the bureaucracy and politicization of nuclear power, and a nuc's life is a living hell.
A nuc never has a nice day <:'-(

NUC
NUC, an acronym for "No Ugly Chicks", can be used in multiple ways. It can be applied to simply represent a woman with an ugly face, as in "did you see that UC?", a label - such as "UC Emily", or as a literal translation of its meaning; "Come to my party - NUC!"

While derogatory, its generally considered good taste not to tell UC's what the acronym means. If confronted as to the meaning by an ugnly female, come up with a definition; "No uninteresting Conversations," etc. It's imperative you dont let an UC know what the definition is - lest you have to look her in her ugly ass face
"DID YOU SEE THAT UC? TOTAL FUCKIN' BIZZARO BITCH!!"
"Hey, invite people to the party, but NUC!"
