Hooligan on the golf course? (5)
I believe the answer is:
rough
'hooligan' is the definition.
(rough can mean a hooligan or violent person)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for rough that I've seen before include "Uneven, harsh" , "Hard - coarse - inexact" , "that driver tries to avoid" , "Jagged" , "grating > below par" .)
