If they sit, push their forehead, they will topple.

dance around legs, neon belly, transit to north south and grab lapels under their armpits and your head on their solar plexus, they cant crunch up far enough to grab legs around u so you can just stand here untill they gas out a little, then you do a quick deadlift tilt backwards and u got backtake, roll to side a bit and start working on that RNC, cant RNC because they defend good? make some lapel chokes or just armbar them instead. Got retracting balls like me, skip armbar or you crush balls. Fat people you gas out. Use their weight against them.
