New, doubly trendy, absorbing record? One's bowled over (7)
I believe the answer is:
ninepin
'one's bowled over' is the definition.
(pins get bowled over in bowling)
'new doubly trendy absorbing record?' is the wordplay.
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'doubly' indicates the doubling of some letters.
'trendy' becomes 'in' ('in' can mean fashionable).
'absorbing' means one lot of letters goes inside another.
'record?' becomes 'EP' (abbreviation for extended play record).
'in' duplicated is 'inin'.
'inin' enclosing 'ep' is 'inepin'.
'n'+'inepin'='NINEPIN'
(Other definitions for ninepin that I've seen before include "What bowler tries to hit" , "target to knock over" , "Skittle" , "over one goes" , "game" .)
