I'm your huckleberry comes from a very classic and hot western movie called tombstone. this phrase means I'm the perfect man for the job.

19th century slang which was popularized more recently by the movie Tombstone. Means "I'm the man you're looking for". Nowdays it's usually used as a response to a threat or challenge, as in the movie.

You play 'Tom Sawyer' and I will be your 'daddy' in this game as Tom 'kinda' looked up to Huck (in my humble opinion). Ala Mark Twain.

And I will jump into your game Like 'Huck Finn', and give you a "shel·lack·ing" (As the most Hon. Sir Sean Connery could only say properly). And we will "tear-this moTHa-out". +))
