I understand that this blunt approach works in the short term, and maybe it's even effective. But trust me, do this for two years instead of just two weeks, and the team stops respecting or trusting each other. Each little verbal jab accumulates over time and deteriorates the working relationship. "Don't work with John or touch his stuff - he goes ape shit every time some little thing happens." There's a good saying that goes "never attribute to malice what can be attributed to incompetence / stupidity / misunderstanding" (the last word depending on your context). Basically, cursing someone out does not necessarily yield results over the long term when there is an underlying problem that can be solved in a more civil fashion.
