Darryl...sounds like you may have watched a re-run of that old classic, "Deliverance" on payTV of late, where one of the hillbillies makes reference to fornicating with a pig, I remember.
I am often amused by the amount of self censorship on this forum. A few choice expletives in the appropriate places adds colour and meaning to everyday conversation.
My understanding of the derivation of that old Anglo Saxon word, [censored], is that centuries ago, a bloke needed the approval of the king, or the king's representative, to marry his wench. On the wedding night they used to put a sign up on the nuptial door that read Fornicating Under the Consent of the King. Facinating how language has evolved over the years.
I suppose appropriateness is the key word. I have learnt never to swear at my crew, but I do swear at myself for making the wrong choice, or that bastard that has just tacked on top of me.
