look up any word, like cunt:
 
24.
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.

3.
A person (usually a medical or law school student) who uses over 3 different colored highlighters, tabs every page in their notebook, and raises their hand after every question asked by their professor, regardless of if they know the correct answer or not. Gunners like to hear themselves speak. They use complicated words to make themselves sound smart even though they have no idea what's going on in class- they pretend they do. They are trying to intimidate you and eliminate competiton.
This gunner in my Chemistry class answers every question the professor asks, asked 5 questions during a 1hr class, and uses 8 different colored highlighters.
