Squirreljak, also known as the 'That’s Nuts' meme, is a unique sub-variant of the Soyjak illustration style that portrays a wide-eyed, open-mouthed squirrel in a state of manic excitement or shock. Emerging from imageboard culture and various Wojak editing communities, the meme satirizes the typical 'Soyface' expression by applying it to woodland creatures. It is most commonly used as a visual pun regarding nuts or as a reaction to absurd and unbelievable news stories. The meme’s charm lies in its hyper-expressive design, which perfectly captures the frantic energy of internet discourse through a rodent lens, often accompanied by the catchphrase 'That's Nuts!'
