Juice box brand (3)
I believe the answer is:
hic
'juice box brand' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for hic that I've seen before include "Involuntary noise cause by a spasm" , "Sound of inebriation" , "Sound of involuntary diaphragm contraction" , "- jacet means here lies" , "In Latin, here and now - ? et nunc" .)
