👉 The term "1997 09" is a joke term that's commonly used to refer to the year of the moon (or if you're more serious and creative, the year of your first date). Imagine saying something like, "Why are we celebrating 1997? Because my first date was in September."
Now for an edgy example sentence using "1997 09": "So, it's time to celebrate! Why not celebrate by getting married and living happily ever after?" This is a humorous way of saying that you're about to marry someone and then wonder why your friends still haven't told you yet. It's like asking 'Why did the chicken cross the road?'
