The phrase 'Large Adult Sons' first gained cultural traction through a 2014 New Yorker article by Alice Gregory, eventually evolving into a widespread internet trope on platforms like Twitter and Tumblr. It describes a specific demographic of grown men who maintain a certain boyish, often boisterous energy, often seen in the company of their parents or in groups of large friends. The meme is typically used to affectionately or ironically mock athletes, politicians, or any group of men who appear oversized yet endearingly immature. It captures the unique dynamic of seeing fully grown men through the lens of 'proud parent' energy, making it a staple for social media commentary on public figures and sports teams.
