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 bike today, but we've experienced a Colorado Bitchslap, so I'm going to do nothing, except watch my car experience a Colorado Carwash.
The literal and/or metaphoric slapping or whacking someone in order to knock some sense into them.
Someone bitchslap the TV producer that keeps putting Vince Guaraldi's "Cast Your Fate to the Wind" on as background music for the weather reports on Hurricane Frances in Florida!
To slap someone (particularly but not necessarily female) who is being rude or nasty, perhaps screaming a lot (i.e., being a bitch). The idea is to get them to calm down and behave. It doesn't necessarily mean you really hit the person; there is such a thing as a verbal bitchslap.
Did you see how Rush Limbaugh stopped spewing that right-wing Nazi bullshit after Howard Zinn bitchslapped him on national television?
Power bitchslap to the face. Must have a big windup and delivered with such force the intended targets head is snapped sideways. Usually handed out by a very pissed off person or big muscley beefcake. Sound of the slap can be heard down the street. Hard enough to pop eyeballs from the sockets and loosen teeth.
