That's funny, some people won't drink it! (3)
I believe the answer is:

(synonyms)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for rum that I've seen before include "Spirit (in the punch?)" , "tipple" , "Alcoholic drink from molasses" , "Queer" , "Odd like drink distilled from molasses" .)
