Though actually, a famous story says it is named after Thomas Crapper, a Victorian plumber whose company made toilets. His name is real, and soldiers in the First World War may have joked about his fixtures, which perhaps helped the word spread — but the word itself comes from crap, not from his surname.

Though actually不過事實上，a famous story says有個有名的說法 it is named after Thomas Crapper說是以 Thomas Crapper 命名，a Victorian plumber whose company made toilets一位維多利亞時代的水管工，他的公司生產馬桶。His name is real他這個人名是真的，and soldiers in the First World War may have joked about his fixtures而且一次大戰的士兵可能拿他的設備開過玩笑，which perhaps helped the word spread這或許幫這個字傳開來——but the word itself comes from crap, not from his surname但這個字本身是來自 crap，不是來自他的姓。

That surname Crapper comes from an old dialect form of cropper, a farmer, which is a different path entirely. Do not tell the story as if the toilet were simply named after him.
