What is with all the goat jokes/facebook groups?

[Adam]

I see more and more Goat groups popping up on facebook. Where did the whole goat thing come from, is it meant to make any sense?

[DIDGEE!]

It's just another stupid string of pointless groups. like all the nan jokes.

I am wondering the same thing - I see all the jokes but have no idea where the whole thing originated from. My guess is that it is just another fad and will soon be over and forgotten.
