I have five things in my mouth and I need them all for me. I own these five things, and I keep them in my mouth so people like you cannot take them from me.
Me, personally, I am quite thirsty so I ask for some “waga” (わが). I have five things in my mouth, so it is hard for me to pronounce the word “water”. So it sounds like “waga” when I ask for it. “Coulg I pweash hab sum waga?! I deed waga!!”
