generally, a Peter Pan is someone who will never grow up.

A term used to reference cannabis/marijuana/weed.

Someone who does not grow up, but can fly.

When doing a girl doggy style the penetrator puts his arms on his hips and continues thrusting as usual thus creating the Peter Pan persona. Once the position has been assumed, Peter Pan should start quoting lines from the movie such as "Just think of happy things, and your heart will fly on wings, forever, in Never Never Land!" or "All you need is thrust and a little bit of pixie dust!" or "If i were you, I'd surrender!".

As epitomized by the boy in the story who never wants to grow up, to be "peter pan" means to be excessively immature.

People who live in an eternal juvenile state.

Verb - When someone jumps out of a high window with no regard for safety.
