Nickname for Florencio, a popular Twitch streamer for Starcraft II, who only plays as the Protoss race and uses unconventional tactics at some of the highest levels of the game. The term was popularised by PiG, another SC2 streamer who describes Florencio's play-style as "sewage" and "filthy", one who swims in the filth and drags his opponents down into the sewage with him. And hence, "sewer mermaid" was born. The term has been used even by Starcraft World Championship announcers to describe unconventional game-play.
