What Is a Pinkie Promise?

Updated 2026-10-28. This page answers: Tell the hand gesture, the show’s oath, and the Roblox game apart.

These words can refer to a hand gesture, the Japanese yubikiri custom, an oath in My Little Pony or a Roblox horror game. This page distinguishes those four uses using the sources below. Other works with similar titles are not identified here.

Evidence and limits

The gesture descriptions are attributed to Wikipedia, the animation oath to the MLP episode references, and the game identity to Roblox. These are separate entities. Unsourced folklore and the novel row without a retrievable catalog record are excluded.

Four things the words can mean

If you meant the Roblox horror game, it is PINKIE PROMISE [HORROR] by Party Cannon Studios, free, Chapter 1 playable since October 2026. The play link is on the home page.

Questions

What happens if you break a pinky promise?

Folklore says different things. The finger-breaking claim on Wikipedia has no citation, so this page does not repeat it as fact.
