A pinkie pie is when you creampie someone who is on there period.

Pinkie Pie swear/promise used in the episode "Green Isn't Your Color" of MLP:FiM. It goes like this: Cross my heart (cross your heart) and hope to fly (mimic the act of flapping wings by moving wrists) stick a cupcake in my eye (pretend to smash said pastry into your eyeball). Said by both Pinkie Pie and Twilight Sparkle.
