Hockey venue that's 'horrible', girl admitted (3,4)
I believe the answer is:
ice rink
'horrible girl admitted' is the definition.
I can't tell whether this defines the answer.
'hockey venue' is the wordplay.
'hockey' becomes 'ice hockey' (synonyms).
'venue' becomes 'rink' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'ice'+'rink'='ICE-RINK'
'that's' is the link.
Can you help me to learn more?
(Other definitions for ice rink that I've seen before include "Skating arena" , "Place to skate" , "Place for skating" .)
