It's called pokebox because "boxes" were where Pokemon were stored in the original games.
actually it was just a random thing some people in the threads did and then it caught on because yeah pokemon are stored in boxes in the games
From what I gathered no one really knows if it's one or the other but it started as an in joke some time around 5-6 years ago
Post Shit then feggit
I'm with you, Pokemon with tits are disgusting
You're in luck, I added a bunch to my collection earlier today
