A student who attends "gifted" classes- special education for those that are more intellectual that the typical student. They may be junior school or high school students.
A classification of the classes. Gifties are usually the smarter, more random, tomboyish person. (At least, our class is...)
Lots of people I know think gifties are freaking retarded nerds. If that's what you think, go shoot yourself, get raped by a rabid goat and left on the street to die.
Person 1: Omigod, look at that person, she's so energetic!
A term originating from Woburn Collegiate Institute, applying to students in the gifted program that spend all their free time in the music hall playing cards.
