The Smart Guy meme, famously known as Roll Safe, features actor Kayode Ewumi from the 2016 BBC Three series 'Hood Documentary.' The image captures the character Reece Simpson pointing to his temple with a knowing smile. It went viral in early 2017 as a way to illustrate 'life hacks' or pieces of advice that are logically sound but practically absurd or humorous. It is one of the most enduring reaction images used to mock poor decision-making and ironic logic across social media platforms like Twitter and Reddit.
