I know we have the over-head cast, the side-arm cast, the single & double haul… but is there a name for the ‘technique’ of turning so your back is to your target and the forecast becomes the backcast, and vice versa? (Typically used, I am told, when there is strong wind at your back when you face your target.)
it’s referred to as the “backassward cast”.
Great name! We use it here on the salt too when the wind is blowing hard from the wrong direction!

Great cast. Very useful when fishing from a boat and you happen to be stationed at your off-handed side of the transom too.
If right handed, for example, and you are on the starboard aft corner of the boat, you cast forward along the right side of the boat and lauunch the line rearwards behind the boat.
Called the ‘resort’ cast. The one you resort to if you can only cast with one hand.
JC - might I add “The one you resort to if you can only cast WELL with one hand”
I can cast with both, but only one works very well
A very useful tactic, but never turn your back to a breaking surf. I once saw someone doing that on a steep beach, and get hit by an extra large wave, which simply exploded on him. He was tossed up in the air, arse over teakettle, dropping the rod in the process. Had there not been a few of us standing close enough to get to him before the next wave, he would have at least lost the rig, and likely been dragged into the surf wearing waders, not a good thing.
Most excellent sir. Thank you for that. You may have saved a life or two and perhaps given a good reason to learn more about casting. 
Or the Ray Charles sight cast?!
Is it still a resort cast if neither arm has a good one?
School teacher’s cast.
I sometimes use it to get a more accurate back cast to avoid the evil branches. They jump out if you’ve got your back turned. I’m sure of it.
Keepeth they back cast out of the freakin’ flora.

Aint that the truth? 
Sayonara Sling? That’s what Mark Seddoti calls his I believe.
I thought that was the cast used for GRASS CARP!!! Or maybe Wood bass or the infamous thornbush trout.
