Not only is dashi soup stock and used in many Japanese dishes, it is also a Japanese sexual term for ejaculation. Kinda gives a new meaning to the soup men, the faceless and nameless heroes whose seishi star in bukkake movies.

naka dashi - naka = inside, dashi = cum ; Cum inside the vagina.

soto dashi - soto = outside, dashi = cum ; Cum outside the vagina - coitus interruptus

Yeh, these types of dashi, more than a mouth full.
