It is! I’ve been watching a bunch of Asian TV shows lately and I’ve seen that phrase crop up in both Thai and Taiwanese shows. I had the same question so I asked a friend who’s Thai about it. She said it’s equivalent to “I should get going”, “I’m going to head out”, or something of that nature.

Wait, so it's more "I go now" than "I go first"?

Well the other person hasn’t gone.
