Invertibral 

invertibral
(adj.) When someone folds like a lawn chair under even mild pressure. Lacking spine, structure, or self-respect. Pretends to have principles but can’t hold a line if their life depended on it.

Examples:

“He went all invertibral the second she raised her voice.”

“Their whole response was invertibral—word salad with no guts.”

“Classic invertibral move: apologize without meaning it and blame someone else.”

"The invertibral waiter gave the intolerable patron a hand job under the table, he found it impossible to challenge a harsh demand"

See also: spineless, weak-willed, bootlicker.

Because of his invertibral nature, he declined the challenge and stood cowering in the corner.

Invertebrate Politics 

The inability of any given political agent to actually respect, comment on or support any position outside of established party lines despite being fundamentally offensive to personal ideology.

So, we should just ignore massive national debt, the endorsement of white nationalism and ridiculous, weaponized tariff impositions that are ultimately paid by US consumers?
Of course! That's how Invertebrate Politics work...it'll be fine. Right?

Invertebrella 

A condition that an umbrella can suffer in a sudden burst of strong wind. Sometimes the condition can be reversed and the umbrella can be saved. Typically the umbrella ends up in the trash and the owner of the umbrella ends up soaked and angry.

Lynda enters the house soaked...

Marty: Whoa, you're soaked! Don't you have an umbrella?

Lynda: I did, but the wind got hold of it and flipped it inside out. I tried to bend it back, but it just broke, cut my finger, and I got soaked. It's in the in the trash.

Marty: Bummer. Bad case of invertebrella huh?

Lynda: What?
