The line comes from Matt Berry's performance as Laszlo Cravensworth, the flamboyant vampire in the television comedy What We Do in the Shadows. Berry is known for his rich, theatrical delivery, and this brief confession captures that style perfectly, turning a villainous admission into a joke.

Its appeal endures because the phrase works in almost any situation where someone is caught enjoying their own mischief.
