The 'So True Bestie. *Pegs You*' meme is a satirical evolution of the 'So True Bestie' reaction format, which initially gained traction on Twitter and Tumblr to mock performative support or overly agreeable internet discourse. The addition of the chaotic action in asterisks transforms a polite, supportive phrase into a surreal and jarring punchline. This specific iteration leans into 'shitposting' culture, where high-contrast tones—sweetness followed by immediate, unexpected aggression—create a sense of absurdity. It is widely used in online communities to signal deep irony, often appearing in threads where one person agrees with a controversial or unhinged take before escalating the situation entirely.
