flyscreen 

A wire-mesh screen over a window to prevent flies from entering a room

I was standing in front of the window and I was looking through the flyscreen.

Fatscreen

When the 4:3 aspect ratio for television is stretched to fit a widescreen 16:9 aspect ratio television making objects and people appear fatter than they actually are.

Dave: I don't like stretching the 4:3 analog image to Fatscreen but at least it gets rid of those annoying black lines along the sides.

Flatscreened 

Flatscreened or Flat-Screened. Used in a devastated tone or manner. Usually when one reaches to grab something they dropped or need. And in the process, slams their head into a flatscreen tv by themselves not noticing or someone else voluntarily catching you off guard which in that sense classifies as Flatslapped, Screenflatted, or Screenslapped

My brother just got flatscreened hard. Goofy fucker didn’t notice the 55 inch television right in front him!

as useful as a fly screen on a submarine 

This saying was conceived by Bob and his buddy Mel while on a cycle ride to Portsmouth Dock Yard via Gosport in the Summer of 1963. They passed by a naval shipyard and noticed a beached and apparently discarded mini (aka: one-person) submarine in the assembly yard. The yard gate was open, so the guys checked out the sub and noticed that it had an open hatch upon which had been placed a fly screen (of the household variety), beggaring the question: "what is as useful as a fly screen on a submarine"??? Ironically, someone had punched a hole through the screen through which a horde of wasps had flown in through the hatch and nested. The thought came to mind of how annoying it would be - after closing up the submarine - to have the wasps buzzing around inside the sub...

Following immigration to Canada in 1975, one of the guys adjusted the saying to: "as useful as a screen door on a submarine" to accommodate Vancouver Island / BC / Canada / North America vernacular (which didn't recognize the term "fly screen").

the act of a Central Bank 'printing' fiat money, ie: quantitative easing, in an attempt to curb inflation is "as useful as a fly screen on a submarine"
