Kate is a girl who accidentally (well could have been deliberate..) did not click "private" when she was sending out invitations to her party via facebook.
I think she lives in adelaide or something?
I got an invite too..
And apparently 600 000 people RSVPed to the event.
The Kate groups are just making fun of what she forgot to do. like "i hope Kate will let me bring a +1" That's saying how Kate's party is going to have heaps and heaps of people...
I only found out who she was today.
