This is needed in the urban dictionary as lol is becoming a waste of time as it is massivily over used.Often people never actually lol, well i dont, So if we use lq we will be telling the truth and lol will again have a meaning.
i like to claim invention to this one:
lq = laughing quietly
since no one ever really laughs out loud this is the newlaughing term for iming, now lol means even funnier.
