The acronym FML most commonly appears in place of the slang phrase, "fuck my life," which expresses disappointment or annoyance at a situation. It appears predominately on the Internet. Other meanings for the acronym include "football manager live," "family medical leave" and "follow my lead."
The use of FML on the Internet occurs in part due to the vulgar nature of the phrase it represents, which many message boards and websites censor.
Usage of FML in reference to family medical leave usually appears in the context of the Family Medical Leave Act of 1993, a federal law. Additional potential meanings for FML include "Facebook markup language," "fluorometholone" and "field manipulation language."
