A phrase typically, but not always, used in
conversation; can also be used in response to a fact, or its opposite, in media; the
appropriate response to any sentence including any variation of the descriptor 'bullshit', when the word 'shit' is being used as a verb, and the preceding perceived assertion or premise reflects a known truth or fact. Also used as its reverse as a prank, to generate belief in something patently false and normally
unbelievable.
