Big noise, no good son! After a long time, comes back (10)

'comes back' is the definition.
(boomeranging is a kind of coming back)

'big noise no good son after a long time' is the wordplay.
'big noise' becomes 'boom' (boom is a kind of noise. I am not sure about the 'big' bit.).
'no good' becomes 'ng' (abbreviation).
'son' becomes 's' (genealogical abbreviation for son).
'after' says to put letters next to each other.
'a long time' becomes 'era' (a long period of time).
'ng'+'s'='ngs'
'ngs' put after 'era' is 'erangs'.
'boom'+'erangs'='BOOMERANGS'
