What does capasa mean in spanish?

Ummm... it really doesn't make a lot of sense. It means, "What's up, please"

If someone said that to you, I guarantee he or she was not a mexican. And if not a mexican, he or she was not fluent in spanish. It was probably some white dude tryin' to seem cool, am I right?

Capasa means, basically, "What's up?"

Por favor means, "please"
