Now LOL, we generally think of as meaning "laughing out loud." And of course, theoretically, it does, and if you look at older texts, then people used it to actually indicate laughing out loud.
Normalmente pensamoque que LOL significa "carcajada" [laughing out loud]. Y, por supuesto, teóricamente lo es, y si nos fijamos en SMS antiguos, se utilizaba para indicar la risa.
