Villainflation 

The addition of extraneous villains into movie sequals.

I can't believe Iron Man 2 was such a mess, but it totally suffered from villainflation.

Villaination 

The Villain Nation is a term created by rapper John Anthony from his 2022 album “Villaination!”.

It essentially signifies one devotion, or fandom, not only to John Anthony’s music, but to ones mentality to always live life Villainous.

I’ve been apart of the villaination since day one.
