Previously an acronym that meant Laughing out Loud, but now people have been getting so lazy that they don't even bother capitalizing it anymore. Now it's just like a normal word to use instead of typing "ha ha ha".
Lol is an abbreviation of laugh out loud. Some people say lots of love but... LOL. Used commonly in texting or... sexting...? Lol.
What is this world about today, lol. The people of earth, what is with you these days, lol. lol I can't stop saying lol,lol. Got nothing else better to do, lol.
