emanate

I'm a little stuck... Click here to teach me more about this clue!

'come out of' is the definition.
(thesaurus)

'last white guy consumed' is the wordplay.
'last' says to take the final letters.
'guy' becomes 'man' (guy can informally mean a man).
'consumed' becomes 'ate' (to eat is to consume food).
The final letter of 'white' is 'e'.
'e'+'man'+'ate'='EMANATE'

'what' is the link.
This may not be correct. It may belong to another bit of the clue.
