LL - stands for "Legit Laughing" and is an alternative to the very standard LOL. People say LOL when they're not really laughing. This created a need for an acronym that could express real laughter by differentiating from the commonly misused lol or it's variations. People now just say LL!
Guy1: LL will eventually replace LOL as the most used internet slang thingie.

Two lower case l's separated by two periods. This is the symbol for Rock On! symbolizing the classic heavy metal "devil fingers" - index and pinky fingers raised whilst the ring and middle fingers are curled down.
