- 250 (number)
250 is the
natural number following 249 and preceding 251.As a Mandarin
slang term, 250 (二百五pinyin èrbǎiwǔ) is an insult meaning "stupid person" or "simpleton". The expression is based on "bàndiàozi" (半弔子 or 半吊子). Inancient China , copper coins were grouped by stringing them together through the square holes in the center; originally 1000 was a unit of currency called a "diao". "Ban diao zi" literally means half a "diao" (500 coins), which is a slang term referring to a person who is inadequate in skills or mental abilities. Since modest Chinese scholars may call themselves "ban diao zi" to humbly deprecate their own expertise, "ban diao zi" is not necessarily a pejorative term. On the other hand, "Er bai wu" (250) is half of a "ban diao zi" and it is an insult.Two hundred [and] fifty is also:
