You are thinking of an overflow action. Spin is created on a very successful defense roll.
And that's kind of what I meant with the "success with style" option that Fate Core presents. If you do a "create advantage" action, which basically is a maneuver, but can be used to create free tags on existing maneuvers as well, you get an additional tag, if you succeed with style, which means you beat the target number by 3 or more.
I've kind of done this already in my pbp game at times. Sometimes I gave 2 additional tags, if both tags go to characters other than the creator of the aspect and things like that, just to spice it up.
