look up any word, like wyd:
When making a promise to someone instead of doing a pinky promise, you engage in a Promise rabbit where both parties make a rabbit ears shape with thier second and third finger put the rabbits together in a scissoring motion then pull away making an explosion noise.

The promise Rabbit is a sacred bond which cannot be broken.
Person 1 - Dude, I promise not to watch adult material on your laptop.

Person 2 - Promise Rabbit Promise

Person 1 - Yes, Promise Rabbit Promise

*does the promise rabbit.
