I have 6 years training in a particularly pragmatic form (Jishukan-ryu) of Jujitsu Alright, now take what you just said and go back the 8 foot tall thing. The whole chain was jokes about how big and tough they were based on OP.
8 whatever pure muscle dude might move pretty quickly. I got beat up by a taller guy once. In my head, it was "get the legs, the giant will fall". His response was early aggression and superior height. You might sound cool, but in reality it can be hard to reach a guy longer than you. Sometimes people are genetically better, whatever technique you think you know will only get you in trouble. Thinking on your feet works better. If you focus on only one attack, you will be creamed corn.
Besides you threatening a joke, you will have to close enough and time that. A giant monster man will be pounding of you/or would have been pounding in you.
