From the Wikipedia article on anal_beads:

In the 2022 Sinquefield Cup, a prestigious chess tournament, reigning World Champion Magnus Carlsen withdrew from the tournament after implying that the opponent he lost to, Hans Niemann, was cheating. An internet meme, first propagated as a joke in grandmaster Eric Hansen's Twitch chat, suggested that Niemann was cheating using anal beads that vibrated the computer-suggested move via Morse Code. The meme spread throughout the internet, even appearing on late-night talk shows such as The Late Show with Stephen Colbert and The Daily Show with Trevor Noah.

Although this originated with anal beads, any use of a sex toy to cheat in chess can be counted under this tag.
