nanto bakusatsu ken
Lit. "South Star Exploding Fist"
A "martial art style" from Hokuto no Ken consisting of throwing dynamite. It was "practiced" by Jackal, one of the minor villains of the series.
Several other bizarre "martial art" styles were labelled as "Nanto Seiken" variants by their users (including but not limited to: human cannonballs, absurdly long polearms, and playing cards), making Nanto Bakusatsu Ken a running gag of the series.
Best summed up by Jackal's iconic quote: "Hey, as long as it works."
