look up any word, like bukkake:
 
1.
The brief moment of silence while driving under an overpass during a heavy rain.
Whoa... that down pause was cool, though brief!

2.
when you're driving down the freeway when its pouring rain, and you go under an overpass or through a tunnel and the rain pauses for a second or two.
its quite exhilarating.
"Wow that was a long downpause, that overpass wasn't even that thick."
"ya that's because traffic is moving so slow"
