I think that "intentionally bad" is a pretty tough thing to pull off. Most of these kinds of films fall into smarmy parody that is too self-aware to have the same charm as the truly unconsciously inept work of our finest bad cinema. Ed Wood thought he was Orson Welles, Tommy Wiseau thought he was Scorsese, the director of Troll 2 was sincerely offended when invited to a screening of his film at a worst film ever festival. It takes a certain amount of blind and brutal gumption to make a transcendently awful motion picture that will reward with years of god-shaming pleasure. The kind of film that makes a witness out of you.
As for camp, I don't think that any of my favorites would qualify as "intentionally bad" even if they challenge the expectations of good taste. Pink Flamingos definitely qualifies here, which is not terrible despite threating to be the worst film of all time for most of its run time. It makes a virtue of its cheapness, in both budget and brow.
There's some films that are favorities of mine that put some people off when they see them on my shelf. But their ignorant prejudices will only deprive them of the subtle joys of schlock. Terrorvision, at 0% tomatometer, is probably my lowest-rated favorite. Tales of the Crypt: Demon Knight is exactly the kind of unloved film that people snicker while passing it by, but it's a quiet masterpiece of unearned thrills. Rubber is neither intentionally bad nor parody, but is the kind of film considered terrible by educated numbskulls threatened by their own mortal lack of comprehension. And these only account for relatively mainstream fare. I leave the entire subgenre of shaggy yeti films to other, more resilient, posters on this site who are even more dedicated than I to exhuming the rich and fecund compost of countless hapless savants of feeble means. Intentionally bad? No. Sincerity is the best accelerant of the brightest bombs.
