Bitch light

To light someone's pipe, bong, or cigarette as they are incapable at the time.

To light your cigarette by holding it up to the burning end of someone else's already lit cigarette and inhaling.

Particularly obnoxious lighting that neighbors sometimes use to flood you’re yard with lights just to annoy you.

A girl that is a bitch only some of the time, and the rest of the time is a perfectly nice girl. Much like the flashing christmas tree lights that are off sometimes and then blink on, but then are off again.
