A special chance meeting at a red light with someone of lesser intelligence who just cut you off and/or sped in front of you so that they could get in front of you. Usually the result of wasteful speeding and/or reckless driving.
An empty Coors Light "cold activated can" left out side of a window to determine if it is warm, cold or "super cold" outside. Works best in colder climates.
Stop light texting is the act of sitting in your car, at an (ideally) long stop light. This is the perfect opportunity to check email, update your FB and scroll through your social media. Typically, if you have teens or children in the car, the act of stop light texting will be rudely interrupted by younger people telling you to stop!
