Occurs while driving. The vehicle in front of you is going below the speed limit (or is going the speed limit where everyone normally speeds), and the road doesn't permit you to pass them, so you become agitated. This builds up, and once you get to a point where you can pass them, you do so dramatically and accelerate hard past them, driving recklessly like a jackass for about 10 seconds before you calm down and return to normal.
Dude, I was going the speed limit. No reason to get Post-Slowed Jackass Syndrome.
