You weren't stupid, it's an oversight, I was more worried you were someone younger when you said you didn't know what it meant, and that is a journey I would not want to send someone young on.
As for the censored word, it's sort of a slang implication of the word, which most things get moronic shortenings because of "slang", and this site's poor algorithm is definitely making everyone else suffer because of that, among other letter sequences used in a similar, if not the same order as many other swears within words that need them.
The only possible word is "Salvage", though I'll type it out.
"Salvage M.E.C. Alternate Build (Okay, I cheated a little)"
Which now spoils my post, all of three people that care about that will be very upset, now.
Yeah, not the most sound idea there, either, now that I think about it. Good point to bring up, really.
