Do that in a Tcraft or a Cessna 170 and you will be on your back before
you can stop your eyeballs on the horizon. It is called a snap- (or
flick-) roll. If you do not know how to fly inverted or recover from
inverted spins, you don't want to explore the possibility.

I accidentally did a snap roll in an S2B once... 90 degree turn at 90
degrees of bank, *quite* a few Gs in the process... Accellerated stall while
banked 90 degrees, but the ball wasn't quite centered... Rotated through the
high wing 270+ degrees and then into a spin headed for the ground... It
happed so quickly that I had originally thought that I had went over the
other way... Of course, since it was an S2B, spin recovery is basically a
non-event...
