A term used to describe someone (usually a female) you work with that is not hot by conventional standards. In normal circumstances this person is not attractive, however, due to your limited options in the workplace (a factory, for example) you find them to be attractive.
I saw Sue from work out at the bar last night and she wasn't looking so good. Clearly she is just factory hot.

A girl that you work with every day in a predominantly male setting who you classify as really hot but when you get her out in the real world you wouldn't pay attention to her.
Stephanie? That girl I work with? She is factory hot only. I saw her at the bar last night and she looked like shit!
