Past tense of 'crap'; used vulgarly to mean defecated, or informally to mean made something worse or failed at something.
The origin of 'crap' is debated; possibly from Middle Dutch 'krappe' (chaff or dregs) or related to 'crappie' (fish), or from a person named Crapper who invented the flush toilet (though this is likely an urban legend). It became slang for feces and failure.
Thomas Crapper didn't invent the toilet, but his name was so perfect for plumbing that people assume he did—so much so that some people think the vulgar slang 'crap' comes from his name, when it's actually the other way around!
