US Army
slang in common use during the Vietnam
War but probably originated during the Korean
War. The phrase has multiple meanings which are dependent on the inflexion used and can usually only be determined from the context of the conversation. Four of the commonest are:-
1 No shit? – Are you giving me the facts?
2 No shit! – I am telling you the absolute truth!
3 No shit. – Don’t give me any lies or evasions.
4 No shit? (A question but with an implicit sneer) – Why don’t you carry on stating the obvious, you
dumb cocksucker?
