Pub garden rage, gulping whiskey -- it's spiked (6,4)
I believe the answer is:
barbed wire
'it's spiked' is the definition.
I can't tell whether this definition defines the answer.
'pub garden rage gulping whiskey' is the wordplay.
'pub' becomes 'bar' (both are drinking establishments).
'garden' becomes 'bed' (I've seen this in other clues).
'rage' becomes 'ire' (ire is anger).
'gulping' means one lot of letters goes inside another (gulp can mean to swallow or consume).
'whiskey' becomes 'W' (phonetic alphabet: alpha, bravo, charlie etc.).
'bed'+'ire'='bedire'
'bedire' going around 'w' is 'bedwire'.
'bar'+'bedwire'='BARBED-WIRE'
Can you help me to learn more?
(Other definitions for barbed wire that I've seen before include "Spiked barrier" , "Deterrent fencing" , "This sitting on the fence?" , "may well put off intruders" , "something to prevent you moving on!" .)
