"So I go on Deviantart, see the usual splatter of MLP art and usually just try to shrug it off, but now it's gotten too hard to ignore. I see people commenting and saying
-"Dat Flank" -"Flankilicious" -"You're flankhurt" -"Kiss my flank" -"She has a big flank"
and other things along this line in which the word flank is substituted for butt. What may be so bad about this you might ask? Well, as an equestrian, I am by all happy when I see the horse world being spread around to people (although MLP is a disgrace to the horse world in my opinion), but when I see it debased like this it just makes me cringe. Bottom line: if you are going to use a word that you learned, especially a term about specific anatomy, know what the hell it actually means!The flank of a horse/pony is not the correct word for its butt! All of those phrases don't make sense!
I don't care what Hub or the writers of the show said, the flank ≠ the butt of the horse/pony. The flank is the horse/pony's side! Get it through your pony-crazed head! If you want to be correct, the anatomically correct word for a horse/pony's butt is rump and occasionally haunches."
