In Chinese slang, the number 250 means 'idiot' (spelled as èr bái wǔ/ㄦˋ ㄅㄞˇ ㄨˇ).[4] The Gulfstream G280 was originally the G250, and was renamed for this reason.[5]
^CHRISTOPHER BEAM (2 May 2014). "The Secret Messages Inside Chinese URLs". The New Republic. Retrieved 12 October 2019. Chinese has plenty of other number-based slang, such as erbaiwu, or "250," which means "idiot," or "38," pronounced sanba, which means "bitch." There are even some streets in China that skip house number 250.
