Bukakke is when several men ejaculate in the face of a woman. The above mentioned description of its origin is false, mainly because since the punishment for
adultery in
feudal Japan was death.
Bukakke is a dish in Japan with fine white noodles with a splash of topping in liquid not at all unlike loads of semen. It comes from the verb bukakkeru which means to splash some liquid (usually water).
The Japanese are very good at making poetic or funny descriptions like that.
All this
mystic bullshit about Japan and japanese customs must please stop.
