An FGL is the best kind of friend that there is. FGL stands for FIFTH GRADE LOVE. It is the most pure kind of love in the entire world. People who have fifth grade love must display it using this acronym at all times. With this kind of love, all other names that this person may be called are obsolete entirely.
