look up any word, like cunt:
 
1.
A regular double barrel shotgun, except someone took the time and effort to saw off a few centimeters from the barrel (and possibly the stock as well). this modified firearm is very useful for short-range crowd-control.
A sawed-off shotgun is easier to hide in a tuxedo than the original shotgun.

2.
when one performs a "shotgun" with two small bullet-style cans
(red bull, bookoo, etc). can become a double barreled shotgun when using regular cans.
