Ullapool Smile
The scars left behind after stapling one's cheeks from the sides of the mouth to the ears, then removing the staples by hand, leaving a series of scars similar in design to a Glasgow Smile.
My work colleague told me about a friend of his in high school who would actually staple his own cheeks with a stapler for fun. He joked that he scars he got didn't create a Glasgow Smile, but rather what he called an "Ullapool Smile".
