When a cat is in the process of cleaning/licking her own ass with at least one back leg/paw diagonally in the air(can also be 2 back legs)...AND at least one, but better with two front paws on the ground rendering the illusion of the cat working an olympic pommel horse.
I looked over my shoulder to see what that smacking sound was....staring back at me was my cat....caught red-handed working the pommel horse.
