What is "Please come to Brazil"?

[Alan]

I hear it all over Tumblr and I still don't know what it means.

They're asking people to fly to Brazil and visit the cornfields

haha, well its basically a thing that started on twitter with people from brazil tweeting celebrities "please come to brazil" and those celebrities tweet them back
its happened enough times for jokes to be made
oh and people from brazil also like to trend things about a certian famous person coming to brazil
so ya, I hope that made sense
