Older woman's company? Flipping saucy stuff! (6)
I believe the answer is:
cougar
'older woman's' is the definition.
(an older woman interested in young men)
'company? flipping saucy stuff' is the wordplay.
'company?' becomes 'co' (abbreviation).
'flipping' shows that the letters should be reversed in order.
'saucy stuff' becomes 'ragu' (Italian sauce).
'ragu' back-to-front is 'ugar'.
'co'+'ugar'='COUGAR'
(Other definitions for cougar that I've seen before include "Big cat" , "Large American feline" , "Cat, aka puma" , "N American mountain lion, puma" , "North American mountain lion" .)
