I have no ideal why they keep using that word? It look as if they were covered in crap and lived in a $hit hole.
I find period terms much more interesting.
I learned “Chunderbucket” from watching “Turn” on AMC. A chunderbucket was an indoor crap bucket. The name came from when they were used at sea. When a sailor prepared to dump the crap bucket overboard he would yell “watch under” so nobody would have their head out a porthole. Watch under was shortened to Chunder.
