If you have watched the Rocket's games of these seasons, and have great passion on this season, i think the best new slogan is : No Pain But Gain.... Just kidding.
"you really don't want to mess with us.... serious, i'm really not kidding." its kinda long, but i think its accurate.
"Ron will punch you if you dont come watch the game" Come now or i'll punch you"(ron artest on a bill board)
