Have you ever created your own moves?

Could be a finisher or just a signature, but have you ever thought up a wrestling move that you hadn't seen before?

A few, with varying quality/creativity:

Second rope springboard senton, slingshotted from the apron.
Swinging cradle into a spinning Brainbuster.
Spinning suplex facebuster, like a reverse Final Cut.
Sitout blockbuster, like the Lay-Out.
Forward facing straitjacket rolled over into a Lay-Out.

I came up with a move that is shared between Devon Slayton and his cousin Celes called the "BNO" or "Black Number One" which the wrestler hits a vertical suplex on an opponent but keeps the hold cinched in as he lifts the opponent up before hitting a twisting vertical suplex but once more he keeps the hold cinched in while lifting up the opponent one more time as he hits a Revolution/Twisting Brainbuster on the opponent, dropping them squarely on top of their head.

The move is named for a favorite song of Celes' amusingly enough.

There's more that I'll add later, but for now the first move that comes to mind is the first one I believe I ever created when I first joined e-feds back in early 2009: the Concussion. It's literally just the same type of jumping spin kick that RVD does for the Van Daminator, but without a chair and to the back of the opponent's head. I also changed the name of it a couple times to the "Shock Value" and then to the "DELETE!" (before Matt Hardy was doing that stuff). But nowadays it's just the Concussion again.

I had a super basic one, never found out if any indie guys used it or not but a Pumphandle Cutter.

Basically, take them into the Pumphandle Drop lift, but then you flip them over into the Cutter/RKO position and drop them.

Vertical Suplex Dropped Into a Flatliner (although I'm sure someone's done it in real life by this point)

Running Punt into a standing moonsault/shooting star press (probably impossible)

A half-shooting star press into a dead drop swanton bomb (sort of like a high angle back senton gone wrong)

A reverse tombstone (Adam Page's "Deadeye")/DDT combo
