An Irish tan occurs when a very pale-skinned Irish person gets too much sun, causing their skin to become even more red and uneven. An Irish tan is not a sunburn; turning red and splotchy is just how some very fair Irish-Americans tan.
My dad thinks he looks good, but that Irish tan is way more red than brown.
