look up any word, like yeet:
 
1.
The instant and simultaneous parting of all motor vehicles on a busy or stationary road when the driver can see the flashing blue lights of a police car or ambulance coming up behind them.
1.Moses held out his hand over the Red sea, and the LORD drove the sea back.
The water was divided, and the Israelites went through the sea on dry ground, with walls of water on both sides.

Hence the flashing blue lights are know as Moses lights due to the power of parting anything ahead of it and driving straight through before the vehicles come back together again.

2.Occasionally on looking in the rear view mirror and being caught off guard by the approaching sirens and flashing lights people have been know to shout "Oh Jesus"..!!!!
