I'm no prude but I've noticed recently an increasing number of nom-de-plumes consisting puns or slight modifications of words and phrases that can only be considered less than acceptable in polite society.
This forum is supposed to be a family show so, folks, think about what you choose as a nickname and those who already have one of those names, think about changing it - you know who you are!
I was not thinking about yours Graham, rather straightforward. But what about (and I do my best to put them in some language you can understand) Fatboy, Crash and A Nickname. The prize goes to the member who posted Praise of Pipex ADSL Server on 22/2 and there's an even stupider one which I cannot find. What are they trying to prove?
I think a lot of them originate whilst under the influence of mind bending substances (legal or otherwise). That is the reason that a number of them make their premiere appearance late on a Friday or Saturday night.
When thought up, they may seem hilarious but, considered in a more sober light they are silly, rude and sometimes insulting.
