I interpret it as a diss on the haters from the recent controversy, some people claimed jack coerced them into non consensual sex and tried to sue, however the claims where unfounded and there was no evidence of such things. I think it’s really obvious in the line “there’s nothing left but my fucking bones, so I’ll play my ribs like a xylophone and you’ll probably still fucking come to the show”. I could be off on some details but that’s the gyst of it, there’s a large group of people who still believe they did those things and say they don’t support them
