Bullshit is what one would call
something that isn't true or he doesn't agree with. Bullshit and Shit do not mean the same thing.
Shit is what one would say when an event does not
work out for him/her. For example , "The illegal bubbling concoction
exploded, causing Dr. Granstein to rip off his tie and scream, 'SHIT!! I DID IT AGAIN!'"
Galileo: The Earth travels
around the sun!
Church: Bullshit! The Earth is at the center of
everything, and everything else revolves around it!
Galileo: Watch as centuries later, my fact becomes utter truth.
Church: You have the devil in you because you spoke ill of the earth!
Go fuck yourself in jail!
