i can't think of absolutely everything off the top of my head of course, but generally my favorite things are:

• horror (especially b-rated).
• body horror and splatterfest movies.
• comedy (like raunchy/dark comedies).
• punk music (egg punk, punk rock, etc.).
• EDM (hardcore, breakcore, etc.).

i like a lot of things that are, regardless of whether or not it's intentional, bad. things that are bad on purpose are just better, and things that are bad on accident are even better.
