The name that is often given to a tattoo that an inked individual later regrets in life. An idiot mark is also something one does that leaves a permanent mark, scar, or disfigurement such as caused by setting themselves on fire with a flame thrower, or doing the eraser challenge.
(My grandfather speaking) You know what this is pointing to arm ? This is my idiot mark. I got it while I was in the Navy and I've regretted it ever since.
( Parent to child ) I've warned you about the eraser challenge, and now you'll have a permanent idiot mark for the rest of your life.
