Cross faces of hopeless young businessmen rolling in debt (6)
I believe the answer is:
hybrid
'cross' is the definition.
(I know that cross can be written as hybrid)
'faces of hopeless young businessmen rolling in debt' is the wordplay.
'faces of' suggests taking the first letters (I've seen 'face of' mean this).
The initial letters of 'hopeless young businessmen rolling in debt' is 'HYBRID'.
(Other definitions for hybrid that I've seen before include "Mix of species" , "Crossbreed or mixture" , "Crossed offspring" , "Offspring of two different species or varieties" , "Genetic cross" .)
