Like big spender in pool? (7)
I believe the answer is:
splashy
'like' is the definition.
Both the definition and answer are adjectives. Perhaps there's an association between them I don't understand?
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for splashy that I've seen before include "Ostentatious" , "catching crabs?" .)
