when you are getting a blow job and when you cut loose you poe/punch the bitch in the rib cage. If properly executed, jiz will shoot out her nose and she will make the noise- SNARK(a perfect snark will have her jumping in circles, one hand to her face and the other waving frantically for some unknown reason.
That hooters chick- I was fucking her face and I snarked her. Then I convinced the dumb cunt it was a accident. I probably wont be able to pull that twice, but I will try.
