It's easily the Hive.

You will say "I don't like Beyoncé's bangs" and about 12 Hive members will have quoted you within six minutes to tell you you're wrong because she has sold x amount and her album is charting at number x and she just won x Grammys and is currently on tour in x and earning x, so her hair looks great.

I rephrased the title because I feel like it wasn't specific enough to what is meant by the OP.

Army

You never hear the Lambs mentioning 90s receipts and clinging to them for dear life.

This isn't particularly unique to any one group, these types of rabid tone deaf stans exist in every base.

But wait...weren't the monsters trading bjs for sales on grindr or whatever? If that isn't doing the most then I don't know what is.

Not when every other week, there would be a thread by a Hive that goes like "Was the 4 era really a flop?"

the Kats did that too. One blew a guy in Walmart for about $3 to get the deluxe edition, I believe.
