“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?
