Gosh, going round university can revolt (6)
I believe the answer is:
mutiny
'revolt' is the definition.
(I know that mutiny is a type of revolt)
'gosh going round university can' is the wordplay.
'gosh' becomes 'my' (both are old-fashioned expressions of surprise).
'going round' means one lot of letters goes inside another (some letters go around others).
'university' becomes 'U' (abbreviation as in UMass).
'can' becomes 'tin' (both are metal containers).
'u'+'tin'='utin'
'my' going around 'utin' is 'MUTINY'.
(Other definitions for mutiny that I've seen before include "Rebellion as on Bligh's Bounty" , "Open rebellion by sailors or soldiers" , "Rebellion in the armed forces" , "Revolt against authority" , "Military rebellion" .)
