Honest to God

Okay kiddo, let me explain what "honest to god" means. You know when you promise to tell the truth and say, "I swear!"? That means you're being really serious and you're not lying. "Honest to god" is kind of like that. It's a way of saying that what you're saying is 100% true and you're not lying at all. It's like a really strong promise that you're telling the truth, and you're not pretending or fooling anyone. It just means you are being completely truthful and honest about something.
