lobuser 

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

louser 

A Welland, Ontario version of the word 'loser'. Defined on Memes of Welland by a spelling mistake when someone called one of the administrators a 'loser' for posting real news, but spelled it 'louser'.

This page is terrible and it should be taken down. You are a LOUSER.

Louser 

Used to describe someone who causes a team to lose while playing a game. Someone who you can never win a game with no matter how hard you carry.

Person I: I can’t believe you made us lose that round Karen.. you’re literally the worst. You better have been trolling and not an actual louser.

louser 

a louser (think houser but with a L) is someone who spends free time doing fuck all. this someone or someones could be doing Something, but that something is actually a meangless waste of time. the someone in question, has no life, no hobbies that matter and is hardly ever productive. lousers may think they help, just by being in the room, but in fact they do not.

nana what are you doing?
playing free cell.
tata what are you doing?
playing solitaire.
jeez! you guys are fucking lousers!
