smoker's thumb

the red and/or peeling skin on the finger, usually thumb, of someone who is new to smoking and/or smokes often because they are inexperienced and the lighter flame touches their thumb or finger

Hey man, what's wrong with your thumb?
Oh, I just started smoking, and now I got a smoker's thumb.
Here, let me show you how to use a lighter!
