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?

Invertebrate Troll 

(N) A cowardice forum troll with extremely low self esteem who no votes others people's posts yet rarely if ever responds with a post of their own.

It seems like all my posts are getting no votes but no one has the balls to respond! It must be the work of Invertebrate Trolls.

invertebrate 

An animal that does not have a backbone. Insects, arachnids, starfish, jellyfish, octopuses, sponges, and corals are all invertebrates.

Invertebrates are the most populated animals on the planet.

interterm goggles 

The curious phenomenon where, those choosing to return for the Interterm break at college find themselves spending inordinate amounts of time with unhealthily few people, altering ones ability to determine hotness or general quality of being in another. See camp goggles.

Wow, that was another wonderful 7 hour chat Suzy McUglybadpersonality, I think I'm in love with you.
Don't be silly Tom, you've just got interterm goggles.
