Team SoloMid, shortened to TSM, was founded in 2009 and became one of the most popular League of Legends organisations in North America. At live LCS matches and international tournaments, supporters began chanting the initials in rhythm, and broadcast microphones picked the cheer up clearly. Clips of the chant spread through highlight videos, forums and streaming culture in the 2010s, becoming shorthand for the fanbase itself. Even after roster changes, creators keep using the audio because three repeated letters instantly identify the team and its era of dominance.
