What is the meaning of “crud”?
As the word crud is shit or often crap (depending on whether this is a swear word or no swear word). I’m wondering if the word “crud” is considered a euphemism for the word “shit”.
What is most unpleasant thing? Thus, it could also cover excreta of all sorts, as well as soap scum, dirt, greasy residues and so on. How does the metaphor of physical substances apply to other things?
