What on earth is crust-punk by the way?

music genre:
punk rock but with extreme metal elements, bassy and dirty (also known as stenchcore)

a type of punk person: panhandling, squatting, and/or homeless punk person who is homeless often by choice (also known as gutter punks)

(they also tend to be associated with each other)

another example of an “older” -punk, if it interests anyone, is splatterpunk, used primarily in the 80’s ^^

definitely rebellious counterculture in its roots as well. very simplified summary is some authors felt stifled that horror was increasingly getting very “literary” and threw everything extreme at the wall

(decent article from 1991 explaining it: here )
