About Fandom: The term “Submas fandom” refers to fans of the Shbway Bosses — a verrrry devoted fandom despite the two being endgame NPCS, having debuted in 2010.

"Submas" comes from the twins' Japanese title "サブウェイマスター", which translates to "Subway Masters" in English — It is a portmanteau of "Subway" and "Masters." Some also use “SBMS” to refer to both twins as well.
