The 'Science Bros' meme highlights the intellectual bond between Tony Stark (Iron Man) and Bruce Banner (The Hulk) within the Marvel Cinematic Universe, specifically originating from their laboratory interactions in 2012's 'The Avengers.' Fans coined the term to celebrate the duo's shared love for complex physics and engineering, often contrasting their high-level genius with the rest of the team's confusion. In meme culture, the template is used to depict two people sharing a niche interest, professional technical knowledge, or understanding a joke that no one else in the room gets. It has evolved from simple fan art into a widely used format for technical humor, academic jokes, and deep-dive fandom discussions.
