Duke Nukem is the sunglasses-wearing action hero of Duke Nukem 3D, the 1996 first-person shooter from 3D Realms, voiced by Jon St. John. His gravelly one-liners became some of the most quoted lines in gaming, and short rips of his voice have circulated on soundboards for decades. Gamers keep using them because three seconds of Duke instantly signals 90s action-movie bravado, which makes even a tiny clip land as a punchline.
