I get hella stoned and watch Foodfight! at least once a year. It’s my “favorite” movie.
Everything about it, from the implied beastiality between Charlie Sheen and Hillary Duff, to the weird gay bat, to the shitweasel 
is a masterclass in what not to do in a movie. It transcends badness and becomes something sublime. The entire plot is about how store brands/generics are Nazis, and one of the Nazis absolutely chews the scenery in a way that makes Brian Blessed look reserved.
Bio dome! It’s horrible, and I love it.
I remember sympathizing with the villain through nearly the whole thing.
The only sane choice when idiots are destroying the planet and blaming you for not being happy about the party, is to go insane and try and kill the polluters.
Filmed largely in Orlando.

Stuff I haven’t seen mentioned yet:
1984 Dune. It’s one of my favorite movies period.
Return of the Killer Tomatoes is on my top 10 favorite bad movies I’d say. Top 20 at least.
The Tune (Bill Plympton movie).
Clue (and very similar Murder By Death)
Empire Records
Cool as Ice (Rifftrax edition)
Actually, on that front - The Room + Birdemic (Rifftrax edition)
Zardoz
Original Little Shop of Horrors
Clue
“Sorry, I meant no meaning yes.”
"No meaning yes?"
Murder By Death
“I found a bullet hole…. Never mind”
How is Clue bad?!
They Live and From Beyond are some of the biggest turds that I love dearly. To a lesser extent, The Room.
Kung pow! Enter the fist.
They said bad movies.
Alien Resurrection. You just can’t watch that garbage without laughing.
The Cat in the Hat (2004) is my pick. I loved it as a kid and I still love it as an adult. Lots of humor for all ages and all the practical props and sets are so neat.
idk, morbius?
Shark Tale
Super Mario Bros. 1993. It is by far the movie that puts the biggest “fun” smile on my face, especially when watching it stoned. It’s so goofy in the best way and comes across as funny in a way that makes me have fun with it every time.
I mentioned Rifftrax in another comment, but the Rifftrax version of this and Street Fighter are two of my favorite things ever.
the amount of slime in that movie makes it impossible for me to watch stoned. Like, if I got that slimey, while stoned, I would be freaking the fuck out. Great movie though. I still love John Luigi-zamo
Another one: Orgazmo https://en.wikipedia.org/wiki/Orgazmo
By the guys of South Park.
August Rush, it’s not even a genre I typically enjoy and it’s so cheesy but I’ve watched it a bunch of times.
Killer Klowns for Outer Space
The Mummy (1999) I believe was panned by critics at release, but I think it’s an absolutely fantastic and humorous adventure film.
It’s a solid 10. Brendan Fraser’s finest work.
