The 'Glizzy Overdrive' meme emerged from the surreal trend of TikTok NPC (Non-Player Character) livestreams, where creators act as if they are controlled by viewer gifts. Popularized by figures like Miles and the broader NPC community, the phrase 'Glizzy Overdrive' occurs when a user sends multiple 'Hot Dog' gifts in rapid succession, triggering a high-speed, repetitive animation and vocal reaction from the streamer. It represents a bizarre intersection of gamified micro-transactions and performance art that captured the internet's attention in mid-2023. The meme is now used to describe moments of sensory overload, frantic activity, or simply to poke fun at the increasingly weird nature of social media monetization.
