Fun Euphemism for Pee

[miniskirtpisser 410]

Encountered this video on Reddit & I love that they use “holy water” as euphemism for woman’s pee. I also love how that second guy enthusiastically drink her holy water.  
 

Is there any other fun pee euphemism that you are aware of?

I like "drain the dragon" (or snake, lizard). Though someone needs to make feminine version, I suggest "drain the daffodil" or "drain the beaver" and make it famous.
