A similar abbreviation to lol, defined 'laughing my tail feathers off'. Expresses amusement, literally laughing, but often used to express even small amusement.
When a board user thinks a discussion about election is funny:
LMTFO I just logged on, and thought you guys were funny for debating my presidential dreams. LOL
