`he` is the guy that put the clue on a forum that I use.
Then his quiz isn't particularly good if you get an answer that fits the clue exactly but is wrong.
ICE (cold) + MAN (guy) = ICEMAN (cocktail drink) is a correct answer in my book.
I feel that I must put in my tuppence worth here. Both bitter and iceman appear to me to be acceptable answers and I would take issue with the setter of the quiz( as pointed out by the alchemist ) If it were me I would discontinue doing any quiz from this source'
An example would be- animal with four legs and a tail(3)
I would think that br for Cold is pushing it a bit.
Surely at least two or more "r"s (Brr!) and that is still a bit dodgy.
Bitter and Iceman both make more sense to me.
