Matt Berry is an English actor and comedian known for The IT Crowd, Toast of London and for playing Laszlo Cravensworth in FX's What We Do in the Shadows from 2019 to 2024. His deep, theatrically precise voice made even throwaway insults sound like formal declarations, and fans began clipping his line readings as reaction sounds online. This insult spread through fan edits and soundboards because it sums up Laszlo's arrogant charm in two words, letting creators borrow Berry's delivery for any smug moment.
