look up any word, like the eiffel tower:
 
1.
The device that seems to be in every traffic light that holds the light green until you get there, then immediately turns the traffic light red. It then holds the light red until someone else comes along from the other direction to set it off again.
Okay, we'll make it in time if we can hit this light green. What the-- !? It suddenly turned red!? %&#$@ stoparrgh!!
