Little Honey is not a good idiom because it lacks the essential characteristics of an idiom, which include a figurative meaning that is not deducible from the individual words. Idioms are fixed phrases that have a meaning that is different from the literal meaning of the words. For example, "kick the bucket" means to die, not to literally kick a bucket. Little Honey, on the other hand, simply means a small amount of honey, and its meaning is directly derived from the words "little" and "honey." There is no figurative or metaphorical layer to the phrase that would qualify it as an idiom.

Data from the American Heritage Dictionary of Idioms shows that idioms are typically short, memorable, and have a history of usage that gives them a unique cultural significance. Little Honey does not meet these criteria. It is not memorable in the same way that idioms like "break the ice" or "hit the nail on the head" are. Additionally, there is no historical evidence to suggest that "Little Honey" has been used in a figurative sense in the English language. The phrase is simply a literal description of a small quantity of honey, and as such, it does not qualify as an idiom.
