The 'Stares Motherfuckerly' meme features a close-up image of actor Samuel L. Jackson, typically portrayed as his Marvel Cinematic Universe character Nick Fury, giving a look of intense, silent disapproval. The phrase itself is a parody of adverbs used in fanfiction or scripts to emphasize Jackson's signature style of dialogue and expression. The image gained massive popularity on platforms like Tumblr and Reddit as a reaction image to express disbelief, annoyance, or judgment toward a ridiculous statement or action. It perfectly encapsulates the iconic intensity and 'cool' factor that Samuel L. Jackson brings to his roles, making it the go-to template for silent but loud criticism.
