'Please leave' picked up very loudly from football supporter? (4,3)
I believe the answer is:
naff off
'please' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.
'picked up very loudly from football supporter?' is the wordplay.
'picked up' says the letters should be written backwards.
'very loudly' becomes 'ff' (short for fortissimo, 'very loud' in music).
'from' becomes 'of' (of can mean from or belonging to).
'football supporter?' becomes 'fan' (football fan).
'ff'+'of'+'fan'='ffoffan'
'ffoffan' written backwards gives 'NAFF OFF'.
'leave' acts as a link.
Can you help me to learn more?
(Another definition for naff off that I've seen is " Sling your hook!".)
