Can you intentionally provoke a movement based Aoo by just moving around in your square without actually moving out of your square? Say for
When you use Acrobatics to move through an opponent's threatened area or space without provoking an attack of opportunity from that opponent, you gain a +2 circumstance bonus on your next melee attack roll against that opponent and that opponent is denied its Dexterity bonus to AC, as long as you make that attack before the start of your next turn.
Canny Tumble is specifically calling out that not just any AoO triggers it, but specifically "use Acrobatics to move through an opponent's threatened area or space without provoking an attack of opportunity from that opponent".
The rules for provoking for moving through an opponent's threatened area specifically call out "moving out of a threatened square".
I don't think performing a distracting act triggers canny tumble.
However, if you're willing to eat the increased difficulty, you could tumble INTO your opponent's space and back into the space you came from. If successful, that would qualify you for canny tumble.
