The 'I Know You're Here Dracula You Big Fucking Nerd' meme features the Marvel superhero Moon Knight aggressively demanding an audience with the famous vampire. While often mistaken for a genuine comic panel, the dialogue is actually a fan-made edit that characterizes Moon Knight as an unhinged, debt-collecting vigilante. It is frequently associated with another viral edit where Moon Knight demands sixteen dollars from Dracula. The meme's popularity stems from the absurdity of a gritty superhero calling a legendary monster a 'big fucking nerd,' making it a go-to template for calling out friends or online personalities in a hilariously confrontational way.
