I'm on my PC now so I can share the ideas that I liked seriously. I don't see the point in choosing a funny name just for the shock value. TGS worked well because it's unexpected but not crude.

[TNT] Stems from Tint'n'Tgs but more to do with Dynamite. Which we are.
[THM]The hallway Monitors is frankly fantastic. Disappointed more aren't agreeing.
[TBW] The Benchwarmers

I like the idea of a one character tag but I don't want to have to force a dumb word to get it to work. Stuff like Stealth and Ultimate are just moronic.

I kind of want it to be serious enough that the name isn't a complete joke but also funny enough to not be taken to seriously. TGS did this very well and I'd like to see something similar.

Just my opinions
