The wetter the better. Squirting is OK, but some of the whole 'pretend it's an orgasm, so lots of screaming' is a bit silly, so I lean towards having girls just unapologetically pissing - it's generally more substantial in quantity, and they don't have to worry about only doing short blasts of water to keep the illusion up.
But anything is better than completely dry, so I'll happily take any kind of fake squirting over that. Call it whatever you want - I just want more girls spraying each other in the face with body fluids.
