A person who, on Microsoft Network (MSN, although most of you bleary-eyed monitor-staring adolescents already know that) repeats the phrase "lol" after every sentence. This word comes from the words "lol" and "abuser." The person usually has no sense of humour and is looking for an inside joke to display as their name, but may be half asleep while aty the computer and using lol as an automatic reflex. Some suspect that human beings were born with the natural instict of responding "lol" to comments (though the theory is not supported by anyone other than, um, me.)
Person 1: i'm back, i just had to go eat dinner.
Lobuser: lol
