The act of going underwater with the exception of your ass and letting out a loud fart. Preferably in the act of an in water dive so as to time it in a manner that you fart as soon as the ass breaches the water. The way a porpoise clears it's blowhole to breathe and reemerge .
When in a pool and you have to fart there is a tough decision to be made. Do you blow bubbles or share with the masses and porpoise poot.

When a male ejaculates so much and hard into a womens mouth that it spews out of her nose like a porpoise coming up for air.

porpoise nose. Flipper talking. Needing to back one out so much that air is escaping while trying to hold it in making a clicking noise. Next stage up from a turtle head.

The verb fora a man to engage in heterosexual sexual intercourse. Used due to the (vague) resemblance of a porpoise to a man's penis. Made famous by Kal Penn playing the role of Taj Mahal Badalandabad in Van Wilder.
Taj: I came here to this country to study the great American art of muff diving. To smack clam, munch rug, dine at just one American pink taco stand! You know, I wanted to, how is it, park the porpoise. You know? I want to take it through the car wash, baby. And get it waxed. I want to wax it. Wax it! You know, and air dry. Air dry that shit, yeah! And I would like to be your assistant very much, Mr. Van Wilder.
