The Guy Tapping Head meme, also known as Roll Safe, features actor Kayode Ewumi as the character Reece Simpson in the 2016 BBC Three web series Hood Documentary. The specific image captures a moment where Simpson points to his temple and smiles while praising someone's intelligence. It became a viral sensation in early 2017, used to mock people who offer 'smart' advice that is actually based on logically flawed premises or terrible decision-making. Today, it remains the ultimate visual shorthand for big brain energy and questionable life hacks.
