'question asked' is the definition.
I know nothing about this answer so I can't judge whether this works.

'tops of burgers burnt at cookout' is the wordplay.
'tops of' indicates taking the first letters.
'at cookout' becomes 'q' (I can't justify this - if you can you should believe this answer much more).
The initial letters of 'burgers burnt' is 'bb'.
'bb'+'q'='BBQ'

'after' is the link.
