I tried searching this, but came up with no results. Anyway, let's revisit established / commonly used names of those dedicated Broadway show fan groups? I think fans of "Rent" are "RentHeads". How about other fan group names of well known shows? Fire away. from Roman in Austin, Texas

"Noel [Coward] and I were in Paris once. Adjoining rooms, of course. One night, I felt mischievous, so I knocked on Noel's door, and he asked, 'Who is it?' I lowered my voice and said 'Hotel detective. Have you got a gentleman in your room?' He answered, 'Just a minute, I'll ask him.'" (Beatrice Lillie)
"established" is a tough word to use in this kind of situation. I'll tell you the ones I've heard used before, but I can't promise that they'll all be "well-known":
In our millions, in our billions, we are most powerful when we stand together. TW4C unwaveringly joins the worldwide masses, for we know our liberation is inseparably bound.

How about CellBlockers for fans of Chicago? It has a nice ring to it, I think. I didn't think of it, but it was from someone directly connected to the show. She was nice enough to come up with a suggestion.

Back in the day when J&H opened in 1997, the "Jekkies" were a very rabid fan base. BTW - J&H ran fro over 1500 performances so somebody had to like it !!
There was a group in the 90s that called themselves the 'Skidoos" that were insane "Chicago" fans.
They were awful. They had a King who dressed in a cape and crown and would induct people into the group in Shubert Alley. Many cast members found them scary and disturbing.
