👉 The Oxford English Dictionary defines "msie" as "a term used to denote a person who is very young, often has a lot of free time and never feels the need for education." The word is commonly used in an edgy way, like when someone says, "She's a MSIE, she doesn't know what she's talking about!"
For example: "I'm sorry, but I don't understand this. It sounds like you're using msie terminology to mean something very specific and not widely known."
