Tin Knocker

Construction slang for a sheet metal worker. A trade far superior to pipe fitting. Only union sheet metal workers can be called this, non union workers are just called dirty rat scab bastards. The only true craftsmen on the job who make what they install... duct work. They are also sick individuals with a twisted world perspective. Also huge dicks. You can see them from space.

That damn tin knocker ran my apprentice off AND shit in my lunch bucket!

noggin knocker

Or often called "double noggin knocker", is a combat move used to take out two assailants simultaneously. Not to be confused with a headbutt... this move is performed by taking the heads of two opponents and cracking them together, with little impact upon oneself.

You see this kind of thing alot in tag team style professional wrestling.

This move seems less effective against pacific islanders, as apparently, their heads are harder than most people's.

Bushwacker Bob made a big mistake when he tried performing a double noggin knocker on the Samoan brothers.
