Bullshit
（重定向自Cowshit）
Bullshit (also bullcrap in the US) is a common English expletive which may be shortened to the euphemism bull or the initialism BS. In British English, "bollocks" is a comparable expletive. It is mostly a slang profanity term meaning "nonsense", especially in a rebuking response to communication or actions viewed as deceiving, misleading, disingenuous, unfair or false. As with many expletives, the term can be used as an interjection or as many other parts of speech, and can carry a wide variety of meanings.
