On the Pot

Loo ● \loo\ ● – Noun – Bathroom.

Gardex l’eau she cried.

“Too late” groused the soused old man.

Chamber pot emptied

From Oxford Living Dictionary and Kottkey:

When people flung their potty waste out of the window, they would shout

“Gardez l'eau” [gar-day low]. That's French for “watch out for the water”. We probably get the word “loo” from this expression. Some people think it comes from “Room 100” which is what European people used to call the bathroom. A third theory refers to the trade name 'Waterloo', which appeared prominently displayed on the iron cisterns in many British outhouses during the early 20th century.
