The 'Costanza.jpg' meme, also known as the George Costanza Reaction Face, features a still of actor Jason Alexander from the hit sitcom 'Seinfeld.' The image captures George with a squinted, skeptical, and smug expression that perfectly conveys a 'get a load of this guy' sentiment. It first gained massive traction on imageboards like 4chan in the late 2000s, where it became a staple reaction to low-quality bait, illogical arguments, or particularly cringeworthy stories. Beyond its 4chan roots, the meme has evolved into a universal symbol for skepticism and dry humor, used across social media to mock or dismiss someone's questionable claims.
