I'll willingly do that for aristocratic male outside (2,7)
I believe the answer is:
'i'll willingly do' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.
'for aristocratic male outside' is the wordplay.
'for' becomes 'pro' (as in being 'pro' something).
'aristocratic' becomes 'noble' (similar in meaning).
'male' becomes 'm' (common abbreviation).
'outside' indicates putting letters inside.
'pro' put inside 'noblem' is 'NO PROBLEM'.
'that' is the link.
Can you help me to learn more?
(Other definitions for no problem that I've seen before include "of course" , "fine" , "Don't worry about it!" , "Easy peasy!" .)
