The Unsettled Tom meme, also known as Concerned Tom, features a distorted, wide-eyed image of Tom from the classic cartoon Tom and Jerry. Unlike most Tom and Jerry memes, this specific image originated from a piece of fanart posted by user Billy_Butcher on Tailsteak in 2012, rather than the show itself. It gained massive popularity on Reddit in early 2019 as a way to portray a person's reaction to a social faux pas or a creepy confession in a mundane setting. The humor typically relies on a 'wait, what?' scenario where the first line describes a normal action and the punchline reveals a context that makes the action horrifying or inappropriate.
