Help me remember a word

I think the word is shit and your mother is a dirty whore.

Batten down the hatches, for a similar nautical term?

Thanks for speaking the superior language, frog.

I can confirm that his mother is a dirty whore

I also think it shows the importance of etymology. A word like fasted combines many meanings in it's old-english usage: fortification, stabling, as well as rationing, which is likely where the its modern usage comes from.

Now it's something hipsters do when they're cleansing.
