The 'You' tweet refers to a viral social media post by Rudy Giuliani on March 28, 2020, which consisted entirely of the single word 'You.' Widely believed to be a direct message accidentally posted to his public timeline, the tweet immediately became a sensation due to its ominous and accusatory tone. Internet users quickly repurposed the screenshot as a versatile reaction image to 'point' at the reader, signify guilt, or answer questions about who is responsible for a particular situation. The meme is a classic example of 'boomer posting' gone viral, thriving on the unintentional comedy of a high-profile political figure struggling with basic social media functionality.
