Stupid place to go with pony not performing (5)
I believe the answer is:
loopy
'stupid' is the definition.
Both the answer and definition are adjectives. Perhaps there's a link between them I don't understand?
'place to go with pony not performing' is the wordplay.
'place to go' becomes 'loo' ('go' can mean 'urinate').
'with' says to put letters next to each other.
'not' is a deletion indicator.
'performing' becomes 'on' (as in being on stage).
'pony' with 'on' removed is 'py'.
'loo'+'py'='LOOPY'
Can you help me to learn more?
(Other definitions for loopy that I've seen before include "Dotty; like a lasso" , "twisted?" , "aerobatic tricks could be so described" , "out to lunch?" , "Mad" .)
