what does rofl stand for

ROFL stands for "Rolling On the Floor Laughing". It is an internet slang initialism used to convey hilarity, especially in text messages, on social media, and other online platforms. It is used to indicate that someone finds something extremely funny. ROFL is similar to other internet slang terms such as LOL ("Laughing Out Loud") and LMAO ("Laughing My Ass Off"), but it conveys a much stronger level of amusement than LOL. The term ROFL originated in the Usenet forum in 1989.
