backstabbing loser 

This is a boy who tells you that he loves you, but really he just wants to lead you on and break your heart. This boy will tell you he loves you and then he will go after your friend, just to make you wish that you were closer to him. Your friends will usually know when a guy is a backstabbing loser, but the backstabbing loser will put up a charade that makes you fall more in love with him and then he will rip your heart out and throw it in the dirt. Your friends will warn you about this person, but you will ignore them and go after him and then regret it immediately.

Girl 1" Wow Marcus is such a backstabbing loser, I can't believe that he told you he loved you and then went after that other girl."

Girl 2 " I know right he is such an awful person.

Meme Loser

A Meme Loser is someone that posts endless amounts of shit, stolen memes, because they're far too stupid to come up with their own. Can be found dwelling in Florida, cowering in the garage from the wife and her flip-flop. When not hiding from the wife, they can be found in truck-stop glory holes, sucking cock in return for memes.

Josh has spent all weekend getting high and stealing other people's work again; he's such a Meme Loser

Live Loser 

A "Live Loser" is generally an 8-16yo who are a pain in the ass all over the internet, especially Xbox live, where they continue to think they rule everything, everywhere. Also known as Trollers, these idiots continue on their tyrannous so called "Reign of the Internet" posting and trying to act cool on various sites all over the internet. They are also people that have absolutely no hope of ever getting laid.

Normal person: "I had such a fun day outside with my real friends and girlriend"

Live Loser: "Well I had lots of fun having cyber sex with my girlfriend I met on Xbox Live and then I completely pwned some n00bs on Halo"

born loser 

This is two different things:
A comic strip that comes in a lot of Sunday newspapers.
And a term for somebody who's pathetic, just can't win, or never seems to do anything right.

I just cant pass any of my tests.....Im born to lose.
