Matt Berry plays Laszlo Cravensworth in the television series What We Do in the Shadows, which began in 2019 and follows a group of vampires living in Staten Island. Berry's over-the-top, old-world delivery made Laszlo a fan favourite, and short clips of his most theatrical lines began circulating among viewers and meme editors. The single-word 'nay' works because it is instantly recognisable even out of context, letting creators borrow Laszlo's arrogant charm for quick rejections without needing any knowledge of the show's plot.
