油淋淋殺人狂(港) (2016)

When a father-and-son relationship gets stuck, just apply a liberal dose of grease. Literally. But what if your dad is a brutal murderer nicknamed the Greasy Strangler? And what if he also tries to interfere with your new girlfriend? And what if he has a gigantic penis? Remember, in an absurd comedy full of psychopaths, never skimp on the lube.
