The line comes from Matt Berry's performance as Laszlo Cravensworth in the television comedy What We Do in the Shadows, a mockumentary following a household of vampires living in Staten Island. Berry's Laszlo is known for his loud, old-fashioned theatricality and sudden bursts of outrage, which made short clips of his dialogue popular for sharing among fans. As a soundboard clip, the blunt dismissal works on its own because Berry's delivery carries the whole joke, and it continues to circulate as a quick reaction for ending conversations.
