ACS Law 

A crude way of calling someone a 'wanker', used heavily between employees at actual UK law firms due to the derogatory nature of being known as a scumbag lawyer like the infamous Andrew Crossley.

RealLawyer: You sound like you're practicing for ACS Law, you utter simpleton.

mother in law

An evil deceptive creature ,who likes to analyze your every move,
Condemn you, and leave you to die.
Often bearing a strong resemblence to Skellator from He-man ,or a Vulture.
Also see " angel of death"
Or "entity from hell"

I would rather have a chainsaw enema ,than have dinner with my mother in law.

- "Gee Gordon, remember that asian bitch you fingered last month? She's fucking insane now. I think she has fallen victim to Gordon's Law."

- "Yeah that bitch be crazy."
