What ticks you off so hard, it'll literally leave you fuming?

First off, I dunno whether the question was formulated that way on purpose or not. If so, that's one hell of a way get someone to spill what peeves them immensely to the point of intense aggravation.
I guess it's safe to say that everything that is in relation to thoughtless, negative duplicity would give me a bad time. Feel free to confirm that.
