air pinkie

After one inserts their pinkie finger into the rectum of their sexual partner and has to hold their pinkie out to avoid getting fecal matter on their other digits or themselves while finishing sexual intercourse.

Frank gave Cindy the old two in the pink one in the sink and had to air pinkie it while they finished having sex. He then scrubbed his finger with bleach.

Pinkie promise 

The most sacred promise anyone can give. When broken, you lose your friend forever. The pinkie promise is done by uttering a chant and doing the motions

AJ: you bettar not tell Twi that ah lost her book. Y'all know what happened last time thayt happened.

RD: Pinkie promise. Cross my heart, hope to fly, stick a cupcake in my eye.

RD crosses a hoof over her heart, opened her wings and gave a flap, and put a hoof to her eye.

AJ: thanks, Dash. Ah really don't know what ah'd do without y'all.

RD: no problem, pal.

*later*

RD listened to Twi talk about her new book she lent to AJ. She bit her lip, and opened her mouth to confess. Suddenly, Pinkie sprung out of a potted plant

Pinkie: you'll lose them. Foreeeeeevveeeerrrrr
She slowly disappeared into the plant.

RD: don't question it...

Pinkie Pie Swear 

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.

Pinkie Pie: Cross my heart and hope to fly, stick a cupcake in my eye! (Pinkie Pie Swear)

Twilight Sparkle: Cross my heart and hope to fly, stick a cupcake in my--AAH! (Pinkie Pie Swear fail)

pinkie wink 

The involuntary muscle contraction of an anus that has been well stimulated by tongue or finder.

After sitting on my face, I knew I had rimmed my man well because he responded with a pinkie wink.
