'foolish' is the definition.

'like figure saving face in imbroglio' is the wordplay.
'like' becomes 'as'.
'figure' becomes 'nine' (a number of figure).
'saving' indicates putting letters inside.
'face in imbroglio' becomes 'i' (I am not sure about this - if you are sure you should believe this answer much more).
'as'+'nine'='asnine'
'asnine' placed around 'i' is 'ASININE'.
