Also known as: グルグルパンチ
Parody of a scene from Grappler Baki, specifically the climax of the fight between Retsu Kaioh and Pickle (Grappler Baki).
After witnessing that his "4,000 years of Chinese martial arts" had no effect on Pickle, Retsu became distraught and mindlessly threw a "cartwheel punch" at Pickle, which results in Pickle quickly biting Retsu's leg off.
