Acrobatic performance European nurses caught on holiday (5-5)

'holiday' is the definition.
Although both the answer and definition are verbs in their base form, I can't understand how one could define the other.

'acrobatic performance european nurses caught' is the wordplay.
'acrobatic performance' becomes 'break' (I can't justify this - if you can you should give a lot more credence to this answer).
'european' becomes 'Dane' (someone from Denmark).
'nurses' is an insertion indicator (nurse can mean to hold onto or harbour).
'caught' becomes 'c' (cricket abbreviation).
'dane' placed around 'c' is 'dance'.
'break'+'dance'='BREAK-DANCE'

'on' is the link.
