What is the difference between LOL and LMAO?
Both mark amusement, but LMAO is the stronger of the two and suggests genuine laughter, while LOL has weakened over time into a general marker of friendliness or lightness. LMAO is also cruder in origin, so LOL is the safer choice in mixed company.
Is it rude to use LMAO at work?
It is best avoided in professional messages. The letters stand for a mildly vulgar phrase, and even where colleagues use it casually it reads as very informal in anything that might be forwarded or archived.
Is LMAO written in capitals?
