Name for a March-May Blizzard, one day it's nice, sunny and 70 degrees, the next day it's a white-out. The weather bitch slaps your brain, and makes it difficult to concentrate, among other things in Colorado that are already distracting you, for example, legalized Marijuana.
Man, I was going to go for a killer climb, hike and biketoday, but we've experienced a Colorado Bitchslap, so I'm going to do nothing, except watch my car experience a Colorado Carwash.
A bitch who squeals and happens to be referenced many times in the book Will Grayson, Will Grayson by New York times best selling authors John Green and David Levithan.
