v. to open a can of beer by putting the middle or index finger under the tab, then jolting the beer out and away from you such that the inertia of the can forces the tab down, opening the can. often results in an explosion, but always results in awesomeness.
n. the act of the above.
I just party opened two 211 tall cans simultaneously. The host is mad because there is beer on everything and because we are at a baby shower.
Nice party open, I hope that beer comes out of the throw pillows.
