maybe you should gave a fuck to this:

LOL, an abbreviation for laughing out loud or laugh out loud, is a common element of Internet slang. It was used historically on Usenet but is now widespread in other forms of computer-mediated communication, and even face-to-face communication. It is one of many initialisms for expressing bodily reactions, in particular laughter, as text, including initialisms for more emphatic expressions of laughter such as LMAO ("laughing my arse/ass off"), ROTFL or ROFL "roll(ing) on the floor laughing"), and BWL ("bursting with laughter"). Other unrelated expansions include the now mostly historical "lots of luck" or "lots of love" used in letter-writing.
