If someone is a bit of an idiot?

[legend.isgod]

If you find someone is a bit of an idiot what should you call them nowadays ?

Over the years there have been many insults bandied about the playground and workplace.
Starting with maybe tube , spass , mong , spastic , mongol , dipsh�t ,retard , and on and on.
Butr since the evnt opf political correctness we shouldnt use such derogatory terms anymore.

So should you call folk backwards ?v Or is that too much ?

Should we juist call folk silly billies or dafties ?
