When you get angry, but a cute angry.
Usually occurs out of jealousy, or short-lived anger towards the opposite sex.

(Reference to the jealousy of Tinkerbell, towards Wendy and Peter Pan)
Boy 1: Dude.. Did you see Anna, when you told Jenn she did a good job on her Science project?
Boy 2: Yeah, man. She totally had a Tinkerbell moment.
