What do you call a person who, with the least amount of contrariness, contradiction, rebuke etc., totally loses his temper and gets extremely upset and starts saying bad words and things like that? A wrathful person?
I know someone who pretends to be all nice and everything, but the moment you contradict him, or tell him he's wrong about something and insist on telling him so, he just flips out and gets all angry and upset and starts shouting and getting vulgar, and he usually does the same when things go bad or not like he wanted etc.
