i randomly think of cool names now and then, and i put them in a list for later use, and pick one that matches the tone when needed (if the battle isn't themed / obvious) ! it's not something i have to try real hard to do, just funny phrases that occur to me

OH good idea im gonna start doing that. a lot of the time i forget i have to name the song until the last second and then i just freeze up LOL. doing it this way would help so much (thank you!)
