A few more... these are very common ones. ^^ afaik = as far as I know imho = in my humble opinion ttyl = talk to you later (as well as ttul) asl = age, sex, location? Asking your details. wtf = what the f***?! You can actually say, "wattafa??" ftw = for the win! Eg. you like marshmallows: "marshmallows ftw" omg = oh my God idk = I don't know btw = by the way (I have actually said "bee-te-wah" in conversation!) <3 = like/love. A heart emoticon. But "I <3 marshmallows" (I like marshmallows) is often said as "I heart marshmallows". rofl = rolls on the floor laughing lmao = laughing my ass off 881 ^^

ttul=Talk to you later LOL=laugh out loudly cu=see you
