1. The third course in the set of five APO LEADS courses.
2. To express the emotion of great success, but only when said success is so overwhelmingly awesome that when you speak of it, your expression must be accompanied by a full pelvic thrust and a slow but deliberate pulling in of the arms (as in a "score!" type of gesture). Use of both arms is encouraged, but not essential.
Use of the gesture must always be accompanied by the motions, and can thus be used out of context at any time for personal enjoyment, or to accomplish the creeping out of other people, whether acquaintances or completely random.
Male Achiever #1: "Yo, I just found out that they're serving tiramisu in the dining hall tonight."
Female Achiever #1: "ACHIEVE!" *pelvic thrust and arm movements*
