Matt Berry plays Laszlo Cravensworth in What We Do in the Shadows, the FX comedy series that ran from 2019 to 2024 and was based on the 2014 film by Jemaine Clement and Taika Waititi. Laszlo's blunt, old fashioned swearing became one of the show's running jokes, and short lines like this were clipped and shared as reaction sounds online. Berry's background in shows like The IT Crowd and Toast of London helped make his delivery instantly recognisable, which is why the phrase keeps circulating long after broadcast.
