I can be dismissive, insensitive, and resentful when I'm in a bad mood. Possible manifestations of anger include deliberately ignoring people, sarcasm, condescendingly correcting petty mistakes, ranting, and (when I'm extremely angry) liberal use of expletives.

Usually, though, I try to keep all those nasty things hidden in my head. In fact, lots of times I don't even know if people notice when I'm angry.
