When you're planning a trip with friends, narrow down your itinerary and agree upon it, and then upon arrival at your destination one friend announces they have scheduled an additional leg. This was done covertly and is to the destination you had previously and jointly decided against.

Once arrived at said additional destination, your friend Facebook posts countless photos intended to solicit envy.
"Hey John, you're not going to believe this... Jeff scheduled a splinter trip to Mendoza, when we agreed to keep the trip just to Buenos Aires!"
