One I just thought of:
When you're listening to someone rant and rave about something that's bothering them, and at a pause where they take a breath, you offer, "Alright." Like a placeholder acknowledgment that you were actually listening to them that whole time they were babbling. But then they go off with, "No, it's NOT alright!" Well good, fuck-o. I'm glad we've established that you only wanted me here so you could pick a fight. Whore.
