Smurfing

A skilled player using a new or secondary account to play against much weaker opponents. Widely hated in competitive communities. "Smurf" originated with Warcraft II players Geoff Fraizer and Greg Boyko, who created alt accounts named "PapaSmurf" and "Smurfette."

Someone who actively and habitually uses smurf accounts to dominate lower-skill lobbies in competitive games — not just someone who happened to make an alt, but someone who does it regularly, often to stomp beginners, boost friends, or dodge rank penalties. A smurfer is generally looked down on in gaming communities: the wins mean nothing, the damage to matchmaking is real, and the behaviour signals deep insecurity about competing at your actual level.

The state of playing so far below your actual skill level — intentionally or on a smurf account — that winning feels automatic. In smurf mode, every decision comes easy, every aim check is casual, every game is one-sided. Players joke about 'entering smurf mode' when they feel unusually dominant in a lobby. It can also describe someone consciously dumbing down their gameplay to carry a lower-rank friend without making it obvious.

(Internet slang) An alternative computer account used by a known or experienced user in order to deceptively self-present as someone naïve or less experienced.

A smurf account or its user.
