Dumbfunkus

Dumbfunkus (noun, informal / internet slang)

A person who:
1. Posts a confidently wrong take online,
2. Is shown clear evidence they’re wrong, and
3. Doubles down anyway—often louder, more hostile, or with worse arguments.

In short: confident ignorance + refusal to update beliefs.



Key traits
• Extreme certainty with weak understanding
Selective reading or goalpost-moving
• “Source?” → ignores sources
• Mistakes confidence for correctness
• Treats correction as a personal attack
• “He got corrected by three experts and still argued—absolute dumbfunkus behavior.”
• “Classic dumbfunkus: wrong, proven wrong, then posts again even harder.”
