Hot, upset with new record in son's game (8)
I believe the answer is:
ninepins
'game' is the definition.
(I know that ninepins is a type of bowling)
'hot upset with new record in son's' is the wordplay.
'hot' becomes 'in' (both can mean fashionable).
'upset' is a reversal indicator.
'with new' becomes 'n' (common abbreviation eg NT for New Testament. I am not sure about the 'with' bit.).
'record' becomes 'EP' (abbreviation for extended play record).
'in' written backwards gives 'ni'.
'ni'+'n'+'ep'+'in'+'s'='NINEPINS'
Can you help me to learn more?
(Other definitions for ninepins that I've seen before include "Skittles, IX objects to be knocked down" , "Bowling game" , "Bowling targets" , "Skittles (IX, not V)" , "Form of skittles" .)
