The line comes from Object Wonderfulness, an animated object show on YouTube where household items compete in goofy challenges. The clip was pulled from a scene tagged around a 'mystery cheese' gag and fans kept the three-second line because the baby-talk delivery is endlessly quotable. Object show fandoms routinely clip these moments into soundboards, and this one spread because it fills the same slot as other confused reaction sounds - a soft, funny way to say a plan is already doomed.

A cutesy voice clip from the object show Object Wonderfulness saying 'me no thinky that worky'. Creators drop it over fail edits when a plan clearly backfires.
This is a three-second voice clip from an animated object show, delivered in a deliberately childlike voice that fumbles the grammar on purpose: 'me no thinky that worky.' The joke lands in the delivery - slow, uncertain, a little smug - as the speaker announces a plan is doomed before it even starts. Creators love it as a sarcastic caption for obviously failing ideas, failed DIY attempts and game clips where the outcome was never in doubt. It works because the broken English makes the insult sound playful instead of mean, so it roasts the fail without roasting the person behind it.
