I&#x27;m an American; it strikes me as an overloaded expression, used to imply both &quot;bullshit&quot; and &quot;testicles&quot;, plus whatever the Sex Pistols were on about in their album title...<p>... yet in C. S. Forester naval stories, it clearly refers to steers or bulls.<p>So, I can only conclude that it is a random operator used to confuse colonials.
