Started by the band Choking Victim and carried on by Leftover Crack, basically a mix of ska-punk, hardcore and reggae. It's not really supposed to be taken seriously, it's just for fun. It's apparently really obscure though, I've never met anyone in real life who has heard of it. https://www.youtube.com/watch?v=YPAIQnlULds https://www.youtube.com/watch?v=WIOsw2wK4os https://www.youtube.com/watch?v=BfKyHfBAD4s
