Did you mean Que Pasa? Que pasa in Spanish means, "What's up?" or "What's happening?"
When someone says ¿Qué pasa?, you actually can respond just as you would in English by saying "Nada mucho." (literally "nothing much" or "not much"). As said earlier, you could certainly say "Lo mismo" - meaning basically the same thing as "same ol' same ol' ".
