two-sworded samurai
Historical term for a samurai who wore two swords (long and short), as was customary for the warrior class. Rare and archaic outside historical contexts.
In the Edo period, the two-sworded samurai was a mark of warrior status.
Literally 'two sticks'. The figurative meaning likely comes from the idea that a person who can be beaten with two sticks and still not resist is a weakling. The historical sense refers to the two swords worn by samurai.
