To get pixie phucked is to have glitter or something else of the sparkling sort be blown into your face by someone else, usually whilst you are on illegal substances.
This is a popular term that is used mostly amongst ravers, but can be applied to anyone.
Person # 1: Whoa, man! I was just pixie phucked a little ago. It was pure beautitude!
Person # 2: Are you rolling?!
