2.
A term used to highlight a combination of elite militancy and knifework. Usually exclaimed while playing violent video games in which people are stabbed with knives, or when multiple idiots are fooling around with knives and trying to be cool. Note that fooling around with knives is a very dangerous thing to do.
Sounds pretty shankalicious.
