When one busts a nut. Then the loose fat on their face begins to shake and wiggle.
I was giving my girl the bilbo baggins when unbenounced to me I busted a nut and performed a Walter Matthau.

The act of screwing a woman with a rather large vagina, that was shaved about 2 weeks prior. An old man with no teeth and a 5 oclock shadow giving you a hummer, slobbering out of the sides of his mouth.
Wow, last night I picked up that old bitch from the bar, went back to her apartment and her box was like The Walter Matthau Mouth!

My scoutmaster tried to blow me at camp. I wouldnt let him, his shit is like Walter Matthau dude!
