L@zerdog, what you described looks like a hybrid between a spin and a spiral.
Once established in the stalled state, the aircraft still had roll control and may have been fairly stable in that state with no further stall breaks, causing confusion as to the correct action to perform.
Spin in the goo, in a CB?
Ouch. (EDIT: Capn Bloogs, thanks, not in a cb, but in the goo nonetheless)
