Matt Berry plays the vampire Laszlo Cravensworth in What We Do in the Shadows, the FX comedy series that ran from 2019 to 2024 and expanded the 2014 film. A gentleman caller is an old fashioned term for a male suitor visiting a woman, which suits Laszlo's centuries old manners and constant innuendo. Clips of Berry's emphatic line readings circulate widely on social media and soundboards, detached from episodes and reused as reaction lines, which has helped this phrase become a shorthand for theatrical flirtation online.
