What map prefix should I use

Hello I’m actually making map for tf2 that doesn’t have any goal, just some map where you can have fun, and my question is what map prefix should I use for it, currently I’m thinking about dm_ .

Trade_.

Please don’t contribute another trade map…

Make a jailbreak map (jail themed map with minigames)

Or, they’ll do what they wanna do, and make a trade map.

What’s wrong with making a trade map? If you mean that there are too many trade maps out there I kind of understand, but maybe it’s because making trade maps is easier, and perhaps more fun for some map makers?
