I am the leader of the TM gang. I am so glad you asked this question.
The TM gang was created by PX herself memeing, she just thought it was neat. Then CC and I copied, and we became the TM gang. EvilTwinNeedle was also a TM at one point, but I don't know much behind his beginning to the TMs, and he wasn't in the og TM gang. It was kinda a big joke on the site last year; we were the big, cool, scary, and gay TM gang. We use the emoji to get it small. By last name changes, in October, half the database was like “omg cool I wanna join the TM gang”, purely because it was just a fun and easy trend to hop on. PX and CC left the Tm gang because of all the new members, as it wasn’t unique anymore. I am the last original member remaining.
It doesn’t mean anything. It’s just a trend lmao, it’ll probably die out soon. I plan on keeping PX’s legacy alive.
Hope this helps!
