Cody "silent" bad stone?

hey ive seen a video of a cody player doing a bad stone but the thing was he was doing the input where cody held his hand on the ground for a split second and he did not say “ha ha.”

Can anyone describe how this silent rock works and if so. Are there any yt vids for more reference thanks!

Perfect badstone. Charge HP Badstone up to level 2 (Minimum 22F charge) release it’ll have twice as long from release -> active than other badstones but half as much recovery. You are +14F on hit minimum with a L2 HP badstone. If the opponent tries to do anything once the attack is actually active it’s most likely blockable.

There is plenty of tech to be potentially explored with it.
