Open Porthole

When you take a dump so large and exhausting that it takes a while for your anus to fully return to full tension.
There is a danger of water getting in if you leave your porthole open

Holy f**k that was a tough one, I think I have an open porthole
I better not take a bath, I might fill up

Frosty Porthole

When you're giving someone head on a yacht and they cum on your monocle (or glasses)

Over the weekend we were out on the water and my bf gave me a frosty porthole.

Rusty porthole

When a woman eats out the ass of a gay/bi cum dump after he's been fucked and filled with cum from multiple men.

I gave him a rusty porthole after he got his ass wrecked in the sling at the gay spa.
