The Onion Knight in Dark Souls 3 is Siegward of Catarina, who returns in the 2016 FromSoftware game wearing the rounded Catarina armour that gives him his nickname. Siegward is repeatedly found stopped in place, humming and hmming while he tries to work out how to get past an obstacle. Players turned those short thinking noises into a standalone reaction clip, sharing the hmm on its own for moments of deep, unproductive thought. It remains popular because the sound instantly signals pondering without needing any dialogue or context from the scene around it.
