Not sure, the mental damage should cause a decent stun on most targets, with barely any chance to adapt, so it's never gonna let you down and stunlock the target with just this one move.
Because the main issue would be how it handles the strength between the robber and the victim. You just have to be quite skilled to practice that move and have enough strength than the robber. Can't fool me with that shit. I already know thats a fucking rickroll since I already seen the whole clip in another site.
