Tunalock is the name given to a trend from BBC Sherlock fandom of creating fanworks in which Sherlock Holmes is a tuna fish. It has given rise to a variety of different works across different mediums and genres, including crack, fluff, humor, porn, memes, and more.
The trend started in 2013 in the break between seasons 2 and 3 of the series, and was sparked off by a Tumblr post created by villain-in-training. Inspired by a joke during a livestream by katzensprotte, villain-in-training drew a piece of fanart featuring Sherlock and John as a tuna and puffer fish respectively, accompanied by a crack backstory. This inspired other fans to create their own takes on "Tunalock".
According to some members of the fandom, Tunalock was a satirical response by disgruntled fans to the pushback around alternate universes starring Johnlock, as well as the backlash towards Sherlock fans generally occurring around the same time. Notably, Tunalock formed part of a larger trend in Sherlock fandom of making fanworks in which Sherlock and/or John Watson are portrayed as animals, such as Fawnlock and Otters Who Look Like Benedict Cumberbatch.
