Scornful sort called out for coffee (5)

I believe the answer is:

mocha

I'm a little stuck... Click here to teach me more about this clue!

'coffee' is the definition.
(mocha is a kind of coffee)

I cannot understand how the remainder of the clue works.

Can you help me to learn more?

(Other definitions for mocha that I've seen before include "Strong dark coffee" , "Kid" , "Fine quality coffee" , "Coffee drink" , "It may end up as grounds" .)
