the bullshit game

i remember playing bullshit card games!
it's like....every person puts down a card and states what the card he/she put has on the pile.
now the person may be lying or telling the truth...we don't know.
that's where the word bullshit comes in.
if any opponent thinks that the person is lying what he had put on the pile, he will say "BULLSHIT!" and the opponent has to open the pile if it was really bullshit.

anyway, this game was played in the movie how to lose a guy in 10 days too. by the way, it's a great movie.

recently, i've been saying and thinking of saying this word many times.
reasons:
i'm bored of hearing lies,
i'm bored of people thinking me as stupid,
i wanna say when it's like a "whatever" statement,
or i say when it ain't matter to me anymore ....like "just do ur own thing"
