This is a game where the person above you wishes for something, and then you grant it with a "But" or a side-effect that renders it useless or pointless, and wish for something as well. For example:
"I wish Ven would bring back On Ebay Today"
"Granted, but Eljay will be hosting it.
I wish that TTV would release Biocraft"
"Granted, but it will be Herocraft!"
I wish everyone forgot the whole "Glowing Dorito" thing.
