Guessing My Name With A Silly Hint

What does “silly goose” mean in American English?

Silly goose is a soft, affectionate American English nickname for someone being a little foolish or absent-minded. It carries no real insult, just gentle teasing. The phrase has a retro, child-coded feeling: parents call kids silly goose, kids call their pets silly goose, and adults sometimes use it on each other ironically. It belongs to a small family of silly + animal names: silly goose, silly billy, silly duck. Other equivalents include goofball, doofus, and knucklehead, all meant warmly.
