This morning my husband was being a baby douche. He thinks everyone needs to hold his hand. When our eleven year old was playing a joke on him, he decided to act like a child and pull her hair. Then he threw a tantrum when I said I would not go to the store and get him cigarettes. He is a grown man acting like a child. Therfore he is a baby douche.
A teenager or very young adult that mistakenly thinks that being a douchebag is cool and who thus essentially becomes an apprentice douchebag that will one day probably become a full fledged douchebag, forever beyond hope of ever becoming a decent human being.
