The Masbro meme features the capybara, the world's largest and most peaceful rodent, often depicted in a state of ultimate tranquility. The name 'Masbro' originated from the Indonesian internet community, combining the local term 'Mas' (older brother) with the universal 'Bro.' It rose to global fame in early 2023, symbolizing a lifestyle of being completely unbothered by chaos. The meme typically highlights the capybara's natural tendency to get along with all other animal species, making it the ultimate icon of stoicism and social harmony.
