A way of saying bulls#@! without offending anyone (although, some people may see it as offensive still. If that's the case, they just don't understand play-on-words in English).

There's also horsh for horses@!#, dosh for dogs%!@ (side note: a euphemism for this would be dog water or dookie).
"Man, that's some bush/bulsh if you think that's gonna work."
"You know what's bulsh? Susan Wojcicki. She's ruining YouTube and is not helping with improving the website overall."
