I would like to know the possible meanings of the words "splibby" and "splabibs" in the first stanza of Harryette Mullen's poem below.  

    Elsewhere on-line I found out a short story with the following dialogue containing "splibby": "You expect me to believe a splibby girl from East Oakland don’t give up nookie?” He starts laughing."   

 or  "The times are changing, splibby. Surprise yourself".

  Any feedback will be really helpful. Thanks a lot, Laumont.

Harryette Mullen's poem:

"spaginzy spagades

splibby splabibs

choice voice noise

gets dress and breath"

These are just nonsense "words", made up by the poet to play with sound.

In terms of parts of speech, 'splibby' sounds like an adjective because it ends in 'y', and 'splabibs' sounds like a plural noun because it ends in 's'.

The writer of the short story is also just playing with the sound of the expression.

Best wishes, Clive
