An older middle-aged woman who works at Target and has a shirt that's obviously too small for her because the split on the side of her work shirt exposes her belly. She is often seen with glasses and yelling at her fellow employees.
Ask anyone at Target about her and they all roll their eyes in disgust.
Person 1: "Look at that woman yelling at all the employees! The one with the glasses!"
Person 2: "Dude, that's Merle. Look at her shirt! You can see her stomach!"
Person 1: "Phooorra! She doesn't look like a pleasant person to be around."
