In older versions of the game (specifically WW, I can't remember if it was the same in CF), you could talk to a villager in another town and try to convince them to move even if they weren't in boxes. After a few visits they would say something like "oh wow, [your town] sounds so cool!" and you had the option to say to them "move in!" or something like that.
I think that's probably where it comes from.
