The human posterior, especially the anus, usually male. Originates from homosexual prison slang of the 1930's - 1960's, in which "junk" is the frontal male genitalia and "candy" the reverse.... A bottom's candy, sexually, is where the top wants to put his junk.
Never mind the big junk, he's candy all the way.
