I hate the phrase 'All-American'

Like when someone says, "Oh she was an all-American girl". 🙄 Because 9 times out of 10, they're talking about a blonde haired blue eyed tanned girl with very basic personality and interests. Please tell me how *that* became the definition of "All-American", especially when blonde and blue eyed isn't even native to the Americas. 🤦🏻‍♀️
