huckleberry

is there a possibility that this word could be used pejoratively as "dumb" fool" or any other meaning besides a common fruit? . For instance H.D Thoreau says he ..."joined a huckleberry party...." In some others parts I've read things like ..."I,m your huckleberry" thank you all.
The OED says:
3. A person, spec. (derog.) a person of little consequence.
[1835 Gent's. Vade-Mecum (Philadelphia) 22 Aug. 2/4 Orson, the wild man of the woods is nothing to himnot a circumstancenot a huckleberry.] 1868 New Eng. Base Ballist 3 Sept. 17/1 Now then, my huckleberry, look sharp! you're wrong! 1889 ‘MARK TWAIN' Connecticut Yankee 338 The Saracen..is no huckleberry.
Perhaps you should submit H.D. Thoreau's passages to OED. They update their sources periodically.

In the movie "Tombstone" Doc Holliday (played by Val Kilmer) often says, "I'm your huckleberry". I always wondered what that meant. He says it with such a great drawl that it's fun to quote.

Michael Quinion has a good response:
I'm your huckleberry.
What it means is easy enough. To be one's huckleberry — usually as the phrase I'm your huckleberry — is to be just the right person for a given job, or a willing executor of some commission. Where it comes from needs a bit more explaining.
First a bit of botanical history. …

The other Doc Holliday quote was, "You're a daisy if you do". What does that mean?
