Creepy because it looks like jizz.



Creepy because of how she's drinking it.



Creepy because I thought it was a human until I saw the other hand.



Creepy because she's communing with Discord.



Creepy because of the look in her eyes.



Creepy because of the position of her wings (DAMN YOU MEMES!)



Creepy because of what she'll probably be coerced into doing next.



I believe that's everything.
