Pinkie scoffed and said "Please, that boy isn't interested in my ass which I think makes him clinically insane, he's only good for pussy.

2. What about Pumpkin?

"Pinkie..." she said "Please don't make me have to suspend you from club activities for the next month and more than that don't make me regret not hiring security guards, I will not allow you to go through any of these doors".

At the rate Rarity keeps hogging all the male animals for herself. Pinkie might as well be suspended already.

Pinkie knows that Pumpkin has no interest in having sex with her whatsoever.

I know I'm late on this but:

3. Send that girl to a mental hospital along with her brother too. Because they both need professional help.
