The Red Shirt Guy meme features Ian Bates, who became an internet legend during a Q&A session at BlizzCon 2010. Bates, wearing a prominent red shirt, famously questioned Blizzard developers about an inconsistency in World of Warcraft lore regarding the character Falstad Wildhammer. His deep knowledge and specific tone instantly turned him into a symbol for dedicated fans and 'lore nerds' everywhere. Today, the meme is used to represent the 'Um, actually' persona, perfect for pointing out technicalities, correcting misinformation, or highlighting niche expertise in any subject.
