A certain writer of how-to-get-women material threatened to sue sosuave because he claimed that he was the first in the industry to use that word and was thus entitled to copyright protection, and therefore no one else could use that word without paying him money.
It is a tenuous legal argument at best, because copyright law only protects creative expressions, and should not be applicable to the use of terms as generic as "w0manese." I think the guy would lose if he did sue. However, intellectual property law is usually determined in practice by whoever can get a lawyer to send a nasty and threatening letter. The other side always caves to the demand, because it is much cheaper and easier than paying lawyers to fight about it in court.
