My thoughts on run through banners when playing against panthers are as follows:
- Pound the panthers (my personal favourite as it can be taken two ways)
- Pickle the panthers
- Paddle the panthers
- Pain the panthers
- Pelt the panthers
- Paddle the panthers
- Pink the panthers
- Pick on the panthers
- Panthers lack passion
- Prevent the panthers
Okay, I'm having way too much fun with that, but you get the idea. The secret is also in the design of the banner, so make it a good one with bright colours and the slogan large so that it can be read. Avoid colours like yellow on a white background and perhaps draw a rectangular star shape around the slogan to make it stand out even more.
Good luck with the game, I hope your team wins!
