Usually, when someone does something to me that would warrant me getting angry, it is usually a remark screamed out the window by some young punk in a car full of kids that has the word ****** in it. So if I catch them at a stoplight, I'll start rubbing my nipples and licking their window... something, anything to get people looking at them and get them embarassed.
And let me tell you, nothing embarasses teenage boys more than a 300lb man in tights rubbing his nipples and licking the windows!
