ag·gra·vate
To rouse to displeasure or anger by usually persistent and often petty goading.
Seems to fit to me.
That's the INFORMAL definition (meaning people have screwed it up so much that it's easily confused). The standard definition of aggravate means to make a problem, injury, or offense worse. You can aggravate a situation. You can't
be aggravated. Trust me, I've had this rule hammered over my head in writing class enough to know.
It's like 'anyway' and 'anyways'. One of them is not a word (hint: the one with the most letters), yet it's frequently used, thus accepted. But it's still wrong.
I mean, no one (except me) is going to stone you for using it in casual conversation, but try slapping it in a professional publication for the New York Times or something, and you're going to get a slap on the hand.
