Wikipedia requires you to be "notable" according to their definition. Here are some of the criterias that may be used depending on the category. Theoretically, only one is enough, but you also needs reliable and independent sources to prove it.

As others have said, making dumb records is probably the easiest ways. If you're music people, starting an obscure/local variation of another genre could be a thing. Making a randomly specific movie can be another relatively easy way. Books can be a solution too, if you get a way to get people to talk about it.
