Depends on what one defines as vulgarity. Open vulgarity or coded vulgarity ie innuendo/double meaning.
I like the comment of legendary British comic actor Kenneth Williams who referred to ‘healthy vulgarity’, a form of comedy which is based on innuendo and its the listener who makes the rude connection, not the comic. Rude, naughty without being open and crude.
The concept of grown adults taking really pleasure in being “naughty” kinda sums it all up.
