Obscene, disturbing and intentionally campy/absurd/awkward/poor taste movies

By over the top I mean like John Waters over the top. Some films that fit what I'm talking about that I've seen are The Greasy Strangler, Pink Flamingos, Hobo with A Shotgun, Creep, Happiness, Bad Boy Bubby. The main element they all share is being ridiculously weird comedic dialogue.
