In the today's world of search engines, everybody can look up a word. We do not need a thread to discuss what it means.

Yes it would mean blacklisting all the derivatives explicitly but that is a lesser evil than the clbuttic solution (nice catch BTW, javispero, I haven't had such a good laugh for months).

Apropos, here's my test: S****horpe.
