Talk acronym (3)
I believe the answer is:
ted
'talk acronym' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for ted that I've seen before include "Spread (hay); yob" , "Heath or Danson?" , "Turnover and spread (hay)" , "The familiar American Senator Kennedy" , "Edward, in short" .)
