abbreviation for "i am like legitly laughing right now". using this acronym, you can still use "lol"(laugh out loud) in ackward or boring situations, because honestly, nobody is actualling laughing out loud when they say "lol". so ialllrn is the new "lol" but it means you actually are laughing out loud. just watch, it will catch on(:
