What is a "bad video game" you have bought as a joke (as in just for the laughs, the lols)?

I bought Ace of Seafood, in which you can play as many kinds of fish that all shoot lasers out or their mouths at other fish.

It's absolutely baffling but probably not how you'd expect.. I found it pretty technical and demanding. It's like a very serious game where you fly F16s and dogfight and destroy aircraft carriers except everything is fish. It's Japanese to the max.

I paid about £6 for it on the Switch, did not play it enough to get my moneysworth. But I think once you hear the concept, you will never stop thinking about it until you try it, so I was glad to be able to stop thinking about it.
