I still run into 'That's just Judo' on the mat. Like Mike, I no longer talk about BJJ on the judo mat - partially because my jits isn't that great to begin with
It usually goes like this for me.
We finally get around to doing some matwork in judo, after the match someone will ask "Why are you so good at matwork, when do you practice?" I respond, "Oh I do that 3-4 days a week". Then they ask where. I mention a bjj club. They say "But why, it's just all ripped off judo anyways.". Then I point out I'm better on the mat then they are, and argument begins.
