A Japanese Gas Pedal is where you sit on the ground face to face with someone and you stick your foot in this person's crotch. Then you grab their ankles and pull. It's a rather painful maneuver that people rarely let happen to them voluntarily.
I was kicking JoJo's ass when he somehow managed to give me a Japanese Gas Pedal. This ended the fight and confused me at the same time, because I could have sworn that he was Chinese.
