The "Can't Prove It" meme features actor Theo Rossi as his character Juan Carlos "Juice" Ortiz from the TV series *Sons of Anarchy*. The image captures Juice looking thoughtful, slightly suspicious, or deeply knowing, often in a dimly lit setting. The meme gained popularity for expressing a strong belief or theory that, while seemingly true or intuitively understood, lacks definitive evidence or proof. It's used humorously to present outlandish or conspiratorial ideas, everyday observations, or shared experiences that people implicitly agree with but cannot formally substantiate. The phrase "Can't Prove It" is typically overlaid on the image, or the image is used as a reaction to such statements, implying a sense of resigned acceptance of an unprovable truth.
