plasteel 

An alloy sometimes used in science fiction, and a combination of the words "plastic" and "steel." It is supposedly an extremely strong metal that is flexible and durable. Notable mentions of this metal can be found in the Star Wars franchise and the video game RimWorld, as well as other media.

The body armor was plated with plasteel, ensuring that it would be easy to wear and provide substantial protection.

plancel

To make plans with the intention of canceling or never following through. Often used if the planceling party is not quick enough to come up with an excuse. Sometimes both parties plancel, and no meeting is intended, the future event is just a social gesture.

(I made this word up, but you should use it.)

The specific plancel:

A: What are you doing on Thursday?
B: (Thinking: I can't come up with anything!) I don't know.
A: Let's go see a movie
B: That would be great. (I'm trapped. I hope he doesn't call, but I'll tell him a family member is ailing if he presses it.)

The two-way, generic plancel:

A: It was so good to see you.
B: You too. Let's do dinner sometime. (We're never doing dinner).
A: Definitely. (We're never doing dinner.)

Planeclapper 

An individual so exuberated from social hierarchy that they willingly and excitedly offer applause upon the landing of an airplane flight.

It was when I found myself engulfed in surrounding applause as the wheels touched ground that I suddenly realized I was on a flight full of planeclappers.
