I went to Louisiana School for Math, Science, and the Arts (LSMSA) in high school. It is a residential high school and we, the students, nicknamed ourselves "gifties." (You didn't actually have to be gifted to get into this public high school. It was for high achieving students throughout Louisiana.)
When I define myself, it's as a LSMSA alum. Hence, the "Giftie." Everything else is the "Etcetera."
Clearly, my friend Stacy feels much the same:
The Best School in the History of Ever
Her post was too touching to keep to myself.
