any of you guys practised a footwork drill where one guy tries touching his partner's legs (inner or outer knee area) or shoulders (you can modify it to the head) and the other guy moves out of the way real quick and try doing the same thing to his partner?

I practice a drill where I try touching womans ass in public.

I usually try to get your mom to do it, but she's too much into it to get any sort of realistic feedback.

I've read that Park Bok Nams students do that type of drill a lot.
