>"What kind of fertilizer have you had your nose in Twilight?"
Did Applejack just imply that Twilight has had her nose in shit?
Of course, in the UK, the former's not really a replacement.
You can make a hallucinogen drug from shit, usually you'd use cow or human shit but horseshit is fine too. It's called Jenkem or something I think.
So yeah, I think AJ just implied Twilight had her nose in shit, and that she's also high. A more straightforward translation would be "What the hell did you smoke?"
There is a reason you didn't get that GET, that answer is so fucking stupid. There are references to everything everywhere, and just because there was a small one that didn't outright say it doesn't mean it should be banned. I bet you would want the Kids Next Door episode where they are drinking rootbeer in a saloon-esque place banned too.
It's a bit different, because cider is an alcoholic drink here. Look at the picture of the kopparberg earlier, the fact that they needed to spell out that one was non-alcoholic.
It'd be like if that episode of KND was made in a country where "beer" just meant rootbeer. That'd cause problems when shown in other countries.
It's the whole "Two countries separated by a common language" problem.
