john wicking means in slang: The Act of John Wicking refers to when you place a bounty on someone’s head that is so large that all the hit men in the world want them dead. The definition was derived from the hit John Wick movie. Keanu Reeves is the target of every international hitman. Being John Wicked is a source of pride and honour. It means that you’re too talented and only a few people can finish the Job. You must therefore be John Wicked to solve the problem. (in Slang Dictionary, added by Pancracio Ruiz)
