Filter out a word (ie grep -v)

mateinone

I have not been able to find it, but I have not been through everything yet either, just some searches.
Is there an option to use the filter to have the opposite effect? So when you type in there it filters out those characters?
I would find this an extremely useful function if it is possible.

no guarantee it will work, though.
