eachself - A word for when you're so selfish you think you can take two

A word for when you're so selfish you think you can take two seats on a plane and still act like you're the hero.

I booked myself twice on the same flight so I could have two seats. I'm a genius. Or I'm just a fool.

Eachself is when you think you're saving money, but you're just being a selfish ass.

I did eachself on a flight. Now I have two seats and no friends. Classic.
