Plural of crapper; slang for toilets or individuals who play craps (the dice game).
From crapper, which may derive from Thomas Crapper (though this is disputed), or from the verb 'crap.' Used colloquially from early 20th century onward.
Thomas Crapper was a real plumber, but he probably didn't invent the toilet—yet his name became synonymous with bathrooms! Sometimes funny etymology beats historical accuracy in the public mind.
