Onionbro, formally known as Siegmeyer of Catarina, is a beloved NPC from the Dark Souls franchise characterized by his distinct onion-shaped armor and a tendency to find himself in difficult situations. He is often found deep in thought, making his signature 'Hmm... Mmm...' sound while contemplating how to overcome obstacles like heavy gates or traps. In internet culture, the Onionbro meme represents a state of being 'stuck' or 'pensive,' used to describe moments where someone is overthinking a simple problem or facing a relatable 'quandary.' The meme celebrates his jolly, though slightly incompetent, heroism and the absurd design of the Catarina armor set.
