Calpone is like another way of saying "word", "cool" or "thats whats up". It is usually used after saying you like someone but also can be used to agree or approve to something.
"I think I like that boy who is sitting in the corner." You say "Ohh Calpone!" or
"I got a new phone." "Oh Calpone"
"I got a new phone." "Oh Calpone"
