I think almost every male NPC in limsa has something to say about their "Stiff masts" or something equally as disturbing.

It's not unlike watching something like Shrek. It's designed for the younger audiences but the tongue in cheek references are there if you are adult/experienced enough to get them.

Cactuar Piss however is a fairly blunt one I'll give you that. Some did have a point above though that "piss" is olde slang rather than the common term it is used for in modern age.
