I think there's a guy on MT who tells a story of dealing with a ninja spider. The guy lost.People who fight have more urgency when someone grabs them by the waist like that. He lacked that urgency and that's what makes me think he had fallen back into point sparring mode and expected the clinch to be broken up. I've seen the same arm movement done in sports where the clinch is broken up. They open their arms as if to say "I'm not the one clinching"
I know I have mine, but it usually involves me coming home late from kung fu practice and me having to fight off dinosaurs and ninjas as the reason why I'm late lol. I figured that people either like dinosaurs or ninjas, so when I get the story going, they will forget that I was late
