When you make a list, most euphemisms for delicate parts or functions have perfectly common usages.

It has always bothered me that so many useful words have been co-opted to coyly refer to 'other' things that they become 'naughty' and provoke giggles or embarrassment.

What is wrong with 'pussy' or 'cock' or 'gay' or a dozen other terms which have classic non-vulgar usages? Most people can surely tell from context what is being discussed. Still, even a neutral use of 'one of THOSE words' in a thread here is likely to draw some pun or smarmy remark unrelated to the topic.

You can find entire websites dedicated to euphemistic expressions for 'dirty stuff', but the list of non-ambiguous words for embarrassing topics is all too short.
