A fan of the pairing of Mabel and Dipper from the show Gravity Falls. Note: They're twin siblings.
"Oh wow. Have you heard of the new ship Pinecest?"
"No. But have you seen BillDip yet?"
"Isn't that a triangle and a young boy?"
"Pinecest is basically incest."

If you like gravity falls, this is the worst.

It's the incestuous shipping of Dipper and Mabel Pines (who are twin siblings)

I hate this, and I hate all who agree with this.
Guy 1: "God I absolutely adore this new shipping 'pinecest'"
Guy 2: "I'm going to kill your family"
Guy 3: "Ya, what the hell dude..."
Guy 1: "u- I'm sorry"
Guy 2: "NO, WHAT THE HELL WAS THAT! OUT, I WANT YOU OUT OF MY HOUSE... NOW!!!"
