It comes across to me as quite puritanical.

There's hardly a single word in existence that can't be turned into an innuendo, or sound the same as a rude or funny word in another language.

If you want to reinforce the notion that cock can only mean penis, this is one hell of a way to do it! Meanwhile, cock is a common term of affection in Northern England ("Cheers, cock", although it might sound more like 'cyock') and also features in the name of countless pubs.

It's one of those things that says more about the accusers.
