Japanese watermelon

A reference to the custom in small Japanese fishing villages to discipline an unfaithful wife by having all the fishermen ejaculate into a ripe watermelon and subsequently the chatting wife had to eat it. However, some women liked it and purposely sought this discipline so it is now used as an invitation to engage in this fetish.

That girl just received a watermelon in her DM's... You know what that means! Japanese Watermelon is crazy!
