1. A term which describes a marijuana cigarette that is significantly larger than one would normally smoke; specific to the use of white, clear, or other cigarette rolling papers, so as to distinguish from a blunt. Origin: unknown.

2., 3., 4., 5., etc. See the other 5000 lame definitions for this word that myself and everyone I know use exclusively for describing a big joint.
1. Stoner One: Dude, I just killed this stock-broker looking dude on the sidewalk by stabbing him in the neck! It sliced his artery and blood sprayed everywhere, drenching myself and passers-by. So I ran off to go clean up at place where no one would notice - DickDonald's. It was pretty sweet, 'cause I was hungry so I grabbed a couple Big Mac's after blocking the bathroom door and deflecting the water in the sink so it sprayed everywhere, allowing me to have a make-shift shower. Anyway, that's not what I'm excited about. I took his wallet, and there's $900 bucks in it! Let's go grab an ounce and smoke gunners all night! Then we can get some hookers!

Stoner Two: Fucking awesome!

Stoner One: You know, this killing-people-and-taking-their-shit thing is pretty cool. I could get used to it.

2. Julie the kindergarten teacher likes to smoke regular sized joints after work throughout the week, but on the weekends she quietly enjoys a gunner while working on crossword puzzles.
