apologies for making most of this an answer ebing a reply to some comments but it was far too long for a comment and i was not willing to making 5+ comments in a row given the wait time in between comments.
Firstly, i do believe Historical Trivia Question are on-topic so long as it still relates to gaming, after all, anything on the nintendo-64 will become Historical Trivia, anything on the nes probably already is Historical Trivia, after all, what doe Nes stand for? would be on topic 50 year from now wouldn't it (provided it wasn't a duplicate).
All knowledge becomes historical as time goes by, to say that all Historical Trivia is off-topic is to say "we wont answer anything about the history which has made us what we are today" and what may have little importance to some may be of great importance to others
@Frank I disagree that there is nothing at all that benefits from asking the origin of a word when it's about gaming, otherwise you have to say that someone asking where "roguelike" originates from is off topic aswell. while it may be Historical trivia later on down the track (if it isn't already) it's foolish and blind to deny that knowing where it originates from is in any not beneficial, i doubt you can explain what "rougelike" mean without explaining it's origins.
While in the linked question "Buff" isn't a gaming unique term touching on it's origins helps in understanding how it's meaning is then conveyed to the term we know in gaming. look at BammaHamma's Answer and the English.SE answer we see where it originated from, how it's meaning has altered/been appended though history and how we can logically see why it is used in gaming in the way BammaHamma described.
Could you answer why L.A Noir is named as it is without explaining where the term Film-Noir originates from which would also include it's meaning?
Good answers always regurgitate what's already been said elsewhere weather it's the internet, books, tv series, any other midea, it's called citing your sources/evidence when providing a factual answer, it makes an answer better, otherwise you making s*** up.
Paul on Modern Family says "W.T.F, Why the Face" when i was brought up thinking "WTF = What The F***". While not about gaming if someone wasn't brought up like me and saw this, they would take WTF as Why The Face, they see it everywhere else and think it is from Modern Family the term originates from, they see a friend down the street depressed and in a chat room or text says "i saw u today, wtf?" and the recipient, knowing that WTF = What the F*** misreads it.
Without knowing the origin they can't grasp the meaning as such this breeds misconception and confusion, if given the argument of which is correct i'm going to regurgitate what's already been said elsewhere in order to prove my point.
you've regurgitate what's already been said elsewhere here by changing
A pregnant cow will stay inside your barn for 20 days, and the baby cow will have half the friendship hearts as its mother
it will take 20 days to give birth to a calf. It will have half the hearts of the mother.
ofcause, if by regurgitate what's already been said elsewhere you mean blanket copy and paste jobs these are going to be shadowed by more impressive answers, hell, i tend to down vote said answers especially if citation markers are left in cause this shows a clear lack of research and understanding of the person's own answer.
