Is it a big party where everyone on the planet is in on it?
Making everyone a pirate?
A party on the moon?
Everyone has so many theories but never seen anything concrete.
Delivering binks sake?
Having a giant sleepover where everyone tells their dream? (Since apparently the one piece is a giant pillow)
I am definitely on the “big party” train.
To me it just makes sense thematically. The warrior of liberation, the freest man in the world would want to unite the whole world and have a huge party. And given everything that would require (uniting the world, getting rid of the World Government as it exists now, helping the various races and tribes get over their grievances and oppression), it tracks for me.
I also like this theory because it’s something ridiculous kid luffy would think of.
I would also highly suggest watching Arturs (Library of Ohara) video about it.

Oh yeah, that’s where I got it from. Artur has a good theory there.
