What is shitter?

The term "shitter" is a slang term, often considered vulgar, for a toilet. It's a more informal and sometimes humorous way to refer to the fixture used for defecation and urination. While the exact origins are difficult to pinpoint, its usage likely stems from the association of the toilet with the act of "shitting" or defecating. The term can also refer to a bathroom or restroom generally, particularly a poorly maintained or unpleasant one. Be aware that using the term "shitter" may be considered offensive in many contexts.
