This is the scar a man received on his arm after being struck by lightning. It's a Lichtenberg Figure, or the pattern made from an electrical discharge. As you can see, it's kinda flowery. Still beats the shit out of any tribal tat though.

Thanks to Marie, who agrees the best scars are the ones you get trying to jam your arm up in a vending machine after your snack gets stuck. Oh this one? Cooler Ranch Doritos.
