Excrement of a male bovine. [language]

What makes bull shit particularly apt for the phrase?

Is it different in appearance, texture or odor from cow shit? Is there any basis at all for the word choice?

I don’t get it.

Anyway, there’s no connection. Bullshit is merely an intensifier of the older use of bull as nonsense.

I dunno…

I seem to recall a comedy movie from 1983: “Bullshot”

It seems that the phrase got adopted over in the UK, but when? And why, if they don’t have cowboys?
