I say this phrase all the time, or at least, think it all the time I’m greeting someone. It took me a really long time to remember where it was from, and since then I’ve felt like a little kid for still saying it.
The original phrase was used in the live action Scooby Doo movie from 2002. Here’s the clip.

Why is this relevant at all? It isn’t. But it’s important (for me) to know where the reference is from. She’s so awkward, it’s perfect.
NOBODY ELSE WILL EVER KNOW.
