onliner 

An onliner is someone who plays CS online and does things which are normally impossible to do on LAN. For example an onliner may HS you while on a ladder or while in mid air. These acts are usually met with agression from players who recieve such ridiculous HS's and thus the term onliner was born.

"Get fuck you stupid onliner, diol"
"Yeah id like to see that online you stupid random"
