Scoff at local boxer devouring book with massage (3,4)
I believe the answer is:
pub grub
'scoff at local' is the definition.
I don't know anything about this answer so I can't judge whether it can be defined by this definition.
'boxer devouring book with massage' is the wordplay.
'boxer' becomes 'pug' (short for pugilist - term for boxer).
'devouring' indicates putting letters inside.
'book' becomes 'b' (abbreviation for book).
'with' is a charade indicator (letters next to each other).
'massage' becomes 'rub' (rub can mean to massage).
'pug' enclosing 'b' is 'pubg'.
'pubg'+'rub'='PUB GRUB'
Can you help me to learn more?
(Other definitions for pub grub that I've seen before include "local courses" , "Food served at a local" , ""Dog and Duck" food" , "Food served in bars" .)
