The 'My Last Brain Cell' meme has become a universal symbol for cognitive burnout, exhaustion, and the inability to focus under pressure. Often featuring a lone character performing a silly dance, looking confused, or barely hanging on while chaos ensues in the background, this meme perfectly captures the feeling of mental fatigue. It rose to prominence across Twitter and TikTok as a way for students and workers to joke about their dwindling productivity during finals week or long shifts. The template is highly versatile, used to illustrate anything from trying to solve a simple math problem to maintaining composure in an awkward social situation when your brain has effectively checked out for the day.
