If A Southerner Says This To You Be Insulted
“Not The Sweetest”
“She’s not the sweetest cookie in the batch, but we wouldn’t trade her for the world.”
Not the “sweetest cookie” just implies that a person is cold or can be a little mean. We’re sure if they heard this insult and it was true they may explode. But the last part of the phrase tries to be endearing. To no avail.
