"Zilch" is American slang for "nothing", i.e, "nil", "zero", "nada", etc.
It is a term of contempt, generally with an overtone of resentment.
For some reason, such terms are many, possibly because of a poetic
tendency to rhyme semantically when trying to speak colorfully:

   You get nothing. Get it?  Nada, nil, zip, zero, zilch.

I'm 53 years old and I've only heard it for the last 30 or so years,
so it's fairly recent, as these things go.

(It's a nice question whether a prescriptivist grammarian would rule that
  "I didn't get zilch"
 was a double negative, or whether it merely used slang inappropriately.)

And, since you asked:

1) There should be an apostrophe in "Hugo's".  The English possessive isn't
   a real case like the Genitive in German; it's an enclitic that attaches
   to the last word of a noun phrase, and to celebrate its semi-inflectional
   status it's spelled with an apostrophe, though it's pronounced identically
   with the -s endings without apostrophes.  And, yes, this *does* cause us
   a lot of grief, as witness a.u.e discussions.

2) there should be a semicolon as below:
    ..it was something like an exclamation ("Zilch!");
      in the novel it was used differently..

   What you have here is a "comma splice", which means putting together
   small sentences with commas, not noticing that each one needs its own
   sentence intonation.

   Unlike the German punctuation rules, which are based on grammar,
   English punctuation rules are based on intonation for the most part.
   Commas refer to a specific intonation contour, and so does the
   period.  The period, of course, stops the sentence; but often one
   wants to continue; that's what the semicolon is for.  It has the
   same intonation as a period but doesn't stop the official sentence.

3) "dictionairies" should be "dictionaries" (ai -> a).  It would be
   pronounced identically, though, if that were the correct spelling.

4) If your intention is to do much formal English writing, you should
   use "a friend and I" instead of "a friend of mine and me" when used
   as a subject.  In situations like that, written formal English does
   not smile on an objective pronoun.  And the "of mine and me" phrase
   seems redundant, anyway; whose friends would we be expecting? :-)

   If, on the other hand, your intention is to learn colloquial American
   youth dialect, let me suggest that many young people would say "me
   and a friend (of mine)" in preference to "a friend of mine and me".
   The parentheses indicate that the phrase is optional; however, since

    a) the objective pronoun is now first in a conjoined noun phrase,
       and needs insulation, i.e, some verbiage to separate it from
       the verb so one can forget what case it was by the time the
       verb arrives; and since

    b) the extra prepositional phrase "of mine" in this case will be
       put at the *end* of the phrase, where it's OK to string things
       out, English being a right-branching language; and also due to

    c) Zwicky's Law, which states categorically that
        "The more irrelevant garbage you put into a sentence,
         the better it sounds.",

   it's quite common to hear "me and a friend of mine".

5) The  past tense of "split" is "split" (i.e, they're identical), not
   "splitted".  There is a small group of English verbs that have this
   property. Virtually all are monosyllabic and end in "d" or "t".
