Over on my favorite Lee-Enfield forum (on jouster.com), there are running jokes about the "dirty word" filter. It doesn't replace words, it just won't let you post until you change them. Oh, and it doesn't give you a hint which word is unacceptable, so you have to do some head-scratching if you weren't posting any actual naughty language.
For instance, "cocking piece" or "cock on close" won't get by the Culvers.
But, with that forum populated largely by ex-military folks, they have a certain way with words, and could make a drill sergeant blush without using a single word not found in the Baptist Hymnal.
