Unpleasant individual recounted gag (5)
I believe the answer is:
retch
'gag' is the definition.
(I've seen this in another clue)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for retch that I've seen before include "Heave (as if to vomit)" , "throw up" , "Sound and seem to vomit" , "Try to bring up" , "Gag, near-vomit" .)
