Spineless men afraid to stand up to POTUS even when he defends Nazis.

The insult given to the gathered members of the London Assembly by London Mayor, Boris Johnson

B. Johnson: "Are you saying they're abdicating their duty to scrutinize me?"
"Are you saying that they haven't the guts to put the questions to me?"
"Great supine protoplasmic invertebrate jellies!"

Inverteboss 

Relative to the word "invertebrate". A boss or leader who has no spine to make tough decisions or stand their ground when confrontations arise. This leader will be influenced by the slightest pressure and will fold their stance instead of holding firm to believed opinions. A title holder with no self respect.

"I can't believe Urban Dictionary rejected my added definition of inverteboss. Guess it didn't have enough obscenities or sexual innuendos included in the description".

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?
