Word Origin and History for bullshit
n.

"eloquent and insincere rhetoric," 1915, American English slang; see bull (n.1) + shit (n.), probably because it smells. But bull in the sense of "trivial or false statements" (1914), which usually is associated with this, might be a continuation of Middle English bull "false talk, fraud" (see bull (n.3)).

v.

by 1942, from bullshit (n.). Related: Bullshitted; bullshitting.
