an accidental dolphin, but on purpose

An exceptionally tight butthole. Said to be as tight as that of a porpoise's butthole, which is water tight.
Damn, I tried to have anal with my girl last night, but she's got a total porpoise hole!. No amount of lube was gonna get my dick in there.

Slap the Porpoise - when you retrieve the bag from a boxed wine. You carry around the bag and "Slap the Porpoise" before drinking directly from the spout. The bag can/is also called "porpoise".

When during oral sex, the ejaculate is so voluminous and forceful that it completely fills all sinuses in the skull, exiting forcefully via the nostrils, possibly ears, and in the rare case, eyes. So named for the both the resemblance in sound and the similar way that porpoises exhale via their blow-hole.
She made me sperm so hard, I ended up giving her a gargling porpoise. She really sounded like one, too. She had to see a ENT doctor.
