It is kind of hard to say because we don't have any visual reference to what we are talking about.
I've seen wild jinking, impressive figure-8 rolling, rolls with wild rudder inputs, short/wide radius high-speed barrel rolls, rolls with high negative G input, and last but not the least, stick-stirring.
Usually all of the above look simular, especially when the relative connection between you and your attacker isn't all that good. The enemy plane slows down in a very quick rate, with its three flight axis(yaw, pitch, roll) not matching its flight path - which is very confusing and discomforting to watch in the attacker's position. The enemy plane is closing rapidly, but you can't get a bearing on the deflection angle so you get wildly confused where to aim at... and then, you overshoot the enemy and tend to think "something's not right".
This is especially true when rolls come with negative G inputs.. I've been accused of stick stirring in the Bf109G(a plane with excellent -G response, but you can't say it has a good roll rate). In truth, what I did was a combination of few maneuvers with absolutely calm stick input: skidding with high rudder input, outside half-barrel roll, reverse the direction of the out-side barrel roll, and then semi-stall out and drop down into a split-S. To the guy attacking I have a good guess how it might have looked like.. the 109 yaw axis changes, not matching the flight path... and then it enters into a barrel roll with its belly outside(very weird to look at), then the direction changes, and suddenly it moves under the nose into a split-S. The guy was probably trying hard to find an aiming point, failed, and watched helplessly as I disappeared under his nose in a split-S.
Therefore, in most cases, I don't think we can say which is stick-stirring and which is not.
Though stick-stirring differs a bit when you examine it closely(the three axis doesn't match the flight path, but the position of the wing tips change in a warping manner... it would roll crazy 90~180 degrees with warp... its different from just "very fast rolls" you would see on a 190), most cases we encounter would be just stick-stirring(yes) in a "legitimate" range. I see a lot of this in newbie pilots I target doing this, moving controls wildly, but not in the manner which would produce micro warps that move the wingtips all over the place.
