Goes wrong having a drink after court (4,2)
I believe the answer is:
acts up
'goes wrong' is the definition.
The definition and answer can be both to do with social activities as well as being verbs in their -s form.
Perhaps there's an association between them I don't understand?
'a drink after court' is the wordplay.
'drink' becomes 'sup' (to sup is to drink).
'after' says to put letters next to each other.
'court' becomes 'ct' (abbreviation used in road names).
'sup' put after 'ct' is 'ctsup'.
'a'+'ctsup'='ACTS UP'
'having' acts as a link.
Can you help me to learn more?
(Other definitions for acts up that I've seen before include "Misbehaves badly" , "Carries on" , "Behaves badly (colloq.)" , "Behaves in a troublesome way" , "Malfunctions" .)
