Raucous area found by knocking shop in US university (4,3)
I believe the answer is:
mosh pit
'raucous area' is the definition.
(area for energetic dancing at a concert)
'knocking shop in us university' is the wordplay.
I cannot quite understand how this works, but
an anagram of 'shop' is 'oshp' which is present in the answer.
'university' could be 'mit' (Massachusetts Institute of Technology) and 'mit' is located in the leftover letters.
No letters remain.
This explanation may well be incorrect...
'found by' is the link.
Can you help me to learn more?
(Another definition for mosh pit that I've seen is " rough dancing area".)
