For knitting (or other crafting/making/doing): a boneheaded, obvious mistake, that someone of your expertise or experience shouldn't have made.
Context: Hank Green is an internet personality and creator of VidCon. He has positioned himself as an authority on a wide variety of topics on his YouTube channel SciShow and as producer & cohost of the channel Mental Floss. In September 2025 he posted a video to SciShow titled "Physicists Don’t Understand Why Knitting Works,” which contained obvious factual errors and many found to be dismissive and misogynistic against knitting as a skill and people who knit. Because of this, it was assumed no one with experience knitting was involved during the production process or final review before the video was posted. Due to the overwhelming backlash he received the video was taken down within three weeks and Green issued a formal apology.
