Smurf

A smurf (in Counter Strike: Global Offensive) is any player who creates an alternate Steam account for the purpose of playing competitive matches against players several ranks lower than their own skill rank. These players use this tactic often because of their inability to be successful at their own given rank, so they must 'Smurf' in order to feel better about themselves. Another popular reason for 'Smurfing' is to give said player the illusion that they are actually close to being good enough to play at the professional level. Although, we all know they will never really amount to anything.
