gabjove
a person who gets excited about stuff kids get excited about and acts like they’re in on the secret
My mom is a gabjove. She knows all the words to the latest kid song and sings it in the car.
My brother is a gabjove. He still plays with Legos and calls them "building blocks."
My friend is a gabjove. He eats pizza for breakfast, lunch, and dinner and says it’s a "lifestyle."
