WATTER!!!

HackneyBaby calls all beverages "water", in the same way I am told by Scottish-born Hackney_bloke that all drinks north of the border are referred to as "juice" (only by some I am sure).

This can lead to confusion. "WATTER!" "You want milky?" "WATTER!!" "You want some juice?" "WATTER!!!" "Oh, you actually do want water. Here you go then."

Bodies of water are also "WATTER!" so it can also mean "sea", "pond", "puddle", or in fact "wee". It also sounds a bit like his word for cat ("CATTA!"), so life at the moment is a constant guessing game, and the conversation above could equally well end with: "Oh yes, the cat has come over the garden wall." It's fun.
