You've just said (in a rare form of German only found in the city of Bristol, England):
"I hate Nightwish, they're shite, I denounce them entirely!! ...but I do love the sound of that Anneke's voice, and I marvel at her dancing."
Weeell, yeah... kind of
...
Anyway, in spanish: agua = water. Thus, agua de Anneke = Anneke's water, which with a little bit of imagination cannot be anyhing different from Anneke's pee.
I don't think Wolfshade loves Anneke to that point... and in case he does, I would prefer not to know.
NP: Ensiferum --- One more magic potion
(nothing to do with the potion above... I hope)
