Josh, visibly angry about guy stealing new carpet (13)
I believe the answer is:
kidderminster
'carpet' is the definition.
(I've seen this before)
'josh visibly angry about guy stealing new' is the wordplay.
'josh' becomes 'kid' (both can mean to joke around).
'visibly angry' becomes 'red' (red in the face).
'about' is a reversal indicator.
'guy stealing new' becomes 'minster' (I am not sure about this - if you are sure you should believe this answer much more).
'red' written backwards gives 'der'.
'kid'+'der'+'minster'='KIDDERMINSTER'
Can you help me to learn more?
(Other definitions for kidderminster that I've seen before include "in the Midlands" , "Carpet town" , "Town renowned for carpets" , "Carpet-making town of Worcestershire" , "Town on the Stour" .)
