Well that took me down a rabbit hole.

For anyone else that’s confused, a “fortnight burger” is a reference to a Rick-roll-type site that displays a picture of wreck it Ralph with his ween out. [Link NSFW]

The now broken URL was fortniteburger.net. and the actual “fortnight burger” is a cartoon burger with its tongue sticking out. It looks like the picture of wreck it Ralph.
