'yay' is the definition.
I don't know anything about this answer so I can't judge whether it can be defined by this definition.

'court house opening doughnuts?' is the wordplay.
'court' becomes 'woo' (both can mean to romance someone).
'opening' suggests taking the first letters.
'doughnuts?' becomes 'oo' (two O's - O resembles a doughnut).
The initial letter of 'house' is 'h'.
'woo'+'h'+'oo'='WOO-HOO'
