look up any word, like cunt:
 
1.
A term used in the US Navy for persons of the Electrician's Mate (EM) rating, exclusively. Often used derisively.
You have three types of nukes: knuckle-draggers, twidgets, and wire-biters.

2.
At NNPTC, navy nuke school, wire-biters are the electrical rates (Electrician's Mates, Electronics Technicians) and generally disliked by the mechanics. They also spend an extra three months in school, which is stupid, since no-one likes nuke school.
Death to wire-biters!
