Matt Berry is best known for playing Laszlo Cravensworth, the flamboyant vampire in the American television series What We Do in the Shadows, which premiered in 2019. His theatrical delivery and old-fashioned insults helped make Laszlo a fan favourite, and short voice lines from the show are widely shared as reaction clips online. Stay Down fits that pattern perfectly, because it is short, instantly recognisable, and easy to reuse whenever a video needs a confident put-down. Its popularity comes less from one viral moment and more from Berry's distinctive performance style.
