Pony General:"Season 12 will never air" edition.

 Spoiler

The meme was either "faic", meaing a very awkward or weird looking face on a character. More likely though, probably the "Dat ass" meme.

 Spoiler

I guess its the "Dat ass" taking in mind the context(Daring making a sassy reply to Ahuizotl demand).

EDIT: Nevermind upon further search I found it's actually "I see what you did there" meme.
