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!
