you realise that etymology
has no place
   in constructing a slang
   lexicon...
or can be derived from such
a branch of spreschen...
    bunking off...
     i.e. playing truant at school...
in poland that's in summary
with only one word -
                   wagary...
      see? etymology cannot penetrate
slang terminology...
     since slang is all about:
terminology, rather tha etymology...
**** me, i love the english version,
it's a verb, rather than a noun -
   bunking off...
      i.e. missing class,
                  or even a whole
day of school...
        it's above the verb-inside-a-noun
that's orthodox english,
   i.e. truancy...
           dissected?
                       playing truant;
and that horrid western slavic
  slang of:    vagary...
        i'm not even going to consider
an etymological focus
                     on the word...
                 wah wah wee wee,
moving philosophy outside
of the per se:
  you sometimes get a pronoun
inside a noun,
        or a verb inside a noun...
  or whatever cocktail might be
asserted, in the "atheistic"
   approach of disbelieving grammar,
was was already done,
   in the schoolyard,
                         with shlang.
