Someone really pathetic. They want to be l33t but even l33t losers consider them to be a loser. The most pathetic form of life.
Get out l0s3r before we h4x0r your c0mp00ter.

Another way to say loser, and also give someone a seizure
L0S3R can also be indeering, and mean a lovable precious nerd who should be protected and shielded from the cruel reality of life.
