Blowing one's nose by blocking one nostril and exhaling quickly out of the other nostril, sending a loogie snot rocket out on the ground. Started in Wyoming by cowboys who didn't want to get their handkerchiefs all nasty with snot.
Dude, I just accidently did a Wyoming blow on someone's shoe. I've got to look back first before doing that.
