The guy who says PP for the first time is funny. The guy who says PP the six millionth time is not funny.That's just your sense of humour being different.
Bluntness deployed in the right way is very funny to some people.
De gustibus non est disputandum and all that.
Similarly go fuck yourself offers no nuance or surprise to be considered nothing more than derogatory profanity. Repetition also drives home the lack of humor rather than enhancing it.
That doesn't mean the target audience can't enjoy it. It just doesn't really qualify as humor.
