Accept that's what to do with beard-grooming product? (4,2,2,3,4)
I believe the answer is:
take it on the chin
'accept' is the definition.
The definition and answer can be both related to thinking as well as being verbs in their base form.
Perhaps there's a link between them I don't understand?
'what to do with beard-grooming product?' is the wordplay.
I cannot really understand how this works, but
'to' is within the answer.
This explanation may well be incorrect...
'that's' acts as a link.
Can you help me to learn more?
(Other definitions for take it on the chin that I've seen before include "facing razor blade?" , "Accept defeat stoically" , "But would featureless wonders > face adversity thus" , "face the situation stoically" , "Be courageous" .)
