Since most of us have learned to use TFG rather than his name,

[TNNurse]

I suggest with use the term "That Court" and leave off the S word...they do not deserve it.

[bucolic_frolic]

1. That's a good idea, I like it

It's a good name for the Extremes

[SheltieLover]

2. Great idea!

[BlueGreenLady]

3. I call it The Extremist Court. n/t

[elleng]

4. Darn, no more

[housecat]

7. National treasures--what a treat! Thanks

[calimary]

9. Those Supremes I love!

The six “others” can go straight to the garbage dump for all I care.

[Snarkoleptic]

5. Since they seem ready to rain-down injustice on us,

I propose we refer to them as PIRs (Politicians in Robes), rather than Justices.

[littlemissmartypants]

16. Or the injustices?

[RockRaven]

6. TRC -- Those Roberts Clowns

Although "clowns" might be too benign of a word...

[niyad]

8. the repuke cabal?

[LoisB]

10. Great idea.

[wnylib]

11. EC - extremist court

Or FC - fascist court

RWC - rightful wing court

[70sEraVet]

12. You can't disparage the Court, because we still have some worthy people on it

But as for the right wing voting block that holds the majority, feel free to use whatever insulting nick names come to mind. And when you combine those nick names with their honorific title, the contrast makes the insult that much better!
The Honorable Justice Witch Burner
The Honorable Justice Pubic Hair
The Honorable Justice Should Have Been Merrick Garland
The Honorable Justice Drunken Attempted Rapey
The Honorable Justice Handmaid In A Weird Cult

[NNadir]

14. I like these too.

[NNadir]

13. I rather like the idea. n/t.

[speak easy]

15. TFC

That eff'ing Court

[brooklynite]

17. Actually "The Court" is a standard abbreviation...

That said, I don't subscribe to snarky nicknames. It doesn't make me feel better and it doesn't make them feel worse. And FWIW, Sotomayor, Kahan and Breyer are still part of "The Court"

[ForgedCrank]

18. I don't

either. I find all the names kind of juvenile to be honest about it.

[TNNurse]

19. Yes, I prefer "That court"

nothing clever or cute.
