Live with bloke consuming egg. Regret! (6)
I believe the answer is:
bemoan
'regret' is the definition.
(synonyms)
'live with bloke consuming egg' is the wordplay.
'live' becomes 'be' (synonyms).
'with' is a charade indicator (letters next to each other).
'bloke' becomes 'man' (informal term for a man).
'consuming' means one lot of letters goes inside another.
'egg' becomes 'o' (an 'o' resembles an egg).
'man' going around 'o' is 'moan'.
'be'+'moan'='BEMOAN'
(Other definitions for bemoan that I've seen before include "Lament, grieve" , "Complain about, lament" , "Deplore, lament" , "Regret, lament" .)
