Hi carol, LMAO means laugh my ass off. There is also a variation on this which is LMFAO but i'll let you work that one out. Also ROFLMAO, roll on floor laughing my ass off. Hope that helps!
yep, that is right and of course lol which means laugh out loud. It's all a bit foreign at first but you soon pick it up. It helps me cause i have a teenager who doesnt even speak English let alone type it! LOL
