seatback 

When leaving a chair, you can say "I call seatback" and no one else in the room can take the seat away from you. Similar to saying, "I call shotgun" when approaching a car.

No way, you can't sit there, I called seatback!"

Setback 

Something that sets you back. It keeps you from doing something and can cause great inconvenience to someones life. A setback may just knock you off your time schedule or it could be stopping you from doing something you drastically need to do. Setbacks are not good, most of the time...

"I really must get my sculpture finished today, but I don't have enough resources to finishes it. That means I'm gonna have to go out and buy some then I'll be off my time schedule. Dang!"

(^^^Not having enough resources to finish his/her sculpture was this persons setback)

front-seat back-seat dilemma 

The inability to decide which seat to take due to the quantity of friends both "kickin' in the front seat" and "sittin' in the back seat." Characterized by indecision and anxiety as the individual has "gotta make their mind up."

A largely ignored condition until early 2011, the "front-seat back-seat dilemma" was widely publicized upon the advent of Rebecca Black's viral single "Friday."

Friend 1 (From the front seat): "Why won't Tim get in the car? I have a dermatologist appointment in 5 minutes!"

Friend 2 (From the back seat): "Dude, give him a break. He's suffering a front-seat back-seat dilemma. Everyone's been there once."
