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"

A person of small stature from Canada who's own life is so bankrupt that he spends every waking moment trying to berate people on Internet messageboards with lame, unwitty insults.

Yeah that trust guy is a real lifeloser.
