"Big Ass Laugh". THE replacement for the much over-used "LOL", spelt BAL. Used when something is so eye-wateringly funny you must laugh on a different level to anything else ever achieved by a "LOL".
"BAL, that is way too funny!", "I am so BALing (Big Ass Laughing) right now!", "That car totally just hit that old man, BAL!", "Did he just eat that moth?! BAL!"
