A term born from the anime 'Nichijou'. It is the combination of 'gun' and 'tsundere' to make 'gundere'. It is the same as tsundere but the cold-like treatment towards the love victim is taken to a new level, incorporating the use of weapons ranging from sub-machine guns to heavy artillery.
The cold-treatment in 'tsundere' is usually just verbal, where as in 'gundere' the cold-treatment is extreme violence via heavy weaponry.
Female (blushing): I-It's not like I'm doing this for you or anything.
Male: I don't really need your help..
Female (extreme blushing): *Fires rocket launcher at the male* I'm going to help you anyway! be grateful!
A technique of inhaling marijuana where one's self puts a bong like object on their lips and pulls a fuse of tobacco and marijuana through a straight pipe and into a small amount of water in the bottom of the bong; The tobacco sets itself as a gauze and the marijuana is on top. The marijuana burns and then the tobacco flares. as this happens the user needs to toke harder as the marijuana and tobacco pulls through creating a gunnie flare. The user will then feel a slight to very large head rush soon followed by a intense stone. It's mean, trust the D.H.B.O.G. (Deputy head boy of gunnies.)
