The Chocolate Panic Picture Show

This list includes very unique and artsy anime that are around one episode in length, so anything between 20 to 50 minutes. So movies and really short stuff are excluded. Also compilations of multiple unrelated anime (ex: Genius Party) would also be here is each episode is in that timeframe.

This interest stack contains mostly obscure OVAs from the 80s/90s (but there are some newer and/or more famous ones as well) that fall into the "so bad it's good" category. These anime are REALLY bad but they still can provide a good laugh with your friends while watching some of the most crappy/WTF/cringe/weird/poorly written/poorly animated/poorly drawn anime.

For some reason, sometimes watching terrible stuff is fun, and if you want a source of this kind of entertainment here you will find plenty of that.

Please notice that this is subjective and the criterion for including an anime in this list isn't its score on MAL but my personal opinion (please don't cry if you find your favourite anime here and you disagree with me about it being bad).

Guaranteed to make you say "what the fuck" or get your money back.

Part 2: https://myanimelist.net/stacks/58801

All OVAs from 1983-1985 that I've found so far. This is the majority of them, but I'm probably still missing a few obscure ones, recaps, or miscellaneous releases. One notable OVA excluded from this period is Cream Lemon, on account of it being a hentai series.

Note: I've seen varying dates for Midori no Neko, which is sometimes listed as 1983. I'll leave it here for now.
