" It is a part of the English culture that for generations has been used as entertainment..."

I can 'usually' tell when an insult is "part of... entertainment" and when it is meant quite seriously. I don't do 'the dozens', but I am aware of the intent....just as I am aware of the intent of some of the intent of certain insults in other threads. "Yo mama" is said as a self-contained line. The words surrounding certain other insults convey a totally different approach.

Back to the (so far) half-dozens...
