What's weird is that when I've, ehr, seen it (porn), there was a lot of it. So much you'd either think that it was inserted and then expelled, a bit like a vaginal enema, making it fake
or that it was pee.
The latter because the urinary bladder is the only thing I can think of down there that would produce that amount of some kinda clear liquid in someone not pregnant.
edit :
Should mention again I've never seen it in real life though so it could be different from what I saw
