Hawaiian Punch rival (3)
I believe the answer is:
hic
'hawaiian punch rival' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for hic that I've seen before include "here in Rome" , "Sound of inebriation" , "- jacet means here lies" , "Involuntary noise cause by a spasm" , "Sound of involuntary diaphragm contraction" .)
