A rash or reddening of the skin between the thumb and pointer finger from holding down the taught waistband of a pair of sweats or boxers to easily access your junk for a good wank. Usually on the left hand, Thumb Burn is only realized after the masturbation session is complete. Every true man gets Thumb Burn once in their life.
