1. 将“bull”与“shit”合并想象。 2. picture a bull with a specific brand or company logo painted on its back, making it appear as if it's advertising or promoting something. 3. As the bull is "proud" (as in "proud" of its brand), it becomes symbolic of exaggerated or insincere boasting, which is what "bullshit" means.
"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)).
bullshit (v.)
by 1942, from bullshit (n.). Related: Bullshitted; bullshitting.
