What does FML stand for?

Excuse me, I'm a bit puzzled. Could you please clarify what the abbreviation 'FML' stands for? I've seen it mentioned in a few cryptocurrency and finance discussions, but I'm not quite sure what it means. It seems like it could be slang or a term specific to this field. Could you help me understand its meaning and usage in this context? I'd appreciate your insight as a professional practitioner in the area.
