Ahh, dude, clean break.

I jumped out of the way of a car that nearly hit me while I was walking (with a WALK sign) in a Georgetown crosswalk. I glowered at the driver, and he stopped the car, lowered the window, and yelled at me, "What the fuck are you lookin' at?!" I remember saying to the friend I was talking to on the phone, "I'm gonna have to call you back." I walked up to the car and kicked it, HARD.

The guy pulled over (double parked) and got out. I could see he was not only bigger than me, but really pissed off. I weighed my options ... and I ran :)

I ran and ran, through crowded sidewalks, diagonally across streets, maybe 15 blocks I skedaddled. Eventually I either lost him or he just broke off the chase.

Anyway, I surely escalated that situation, but it all started with me staring him down.

I wouldn't recommend handing out "glowering" looks. (I had to look that word up btw :D). Someone will eventually accept your challenge.
