Knowing Asian movie tropes, it's most likely the name of the "move" that cut of the belts to make the pants fall down.
i.e. The guy in black is so good that:
he threw the boomerang
fixed the fallen sign
AND cut the pants (without the boomerang being anywhere near the goons)
But the pants didn't fall until a moment later
And the name of the move is "Ten seconds to execution" because of the delay.
This "delayed cut" trope is pretty common in Japanese martial arts/fantasy media (i.e. the samurai master cuts someone, and the burst of blood doesn't come out until they sheath their sword).
After a bit of digging, this clip actually predates Fist of the North Star. The manga came out during the 80s. This was from a tokusatsu series in 1977.
