"That depends on the context of the sparring/wrestling. Again… context is everything. If you're doing that against a beginner who's trying to apply something he's just learned, you're a jerk. If it's a couple of more seasoned practitioners, it can be fine, even expected as part of the "enhancement" of technique, and could be classed as resistance. Then again, if you're rolling to achieve a particular aim, it could still be classed as a jerk action."
So I am being accused of something with a seriously fuzzy definition. And why my bad partnering idea came with a definition.
In mma there is a whole bunch of stuff That is seen as pretty low brow and yet are viable techniques. It is a terrible way to spar someone in that it is just mean. But we have to acclimate people to the concept. I would have called that being a jerk.
