difference between "pookie" and "bookie" (taught by Mr. Cox)

Pookie - BAE (Before Anyone Else), Partner, Significant Other, and/or Spouse.

       EX - My wife's name is Karen, she is my pookie.

Bookie - Friend, Co-worker, and/or Acquaintance.

       EX - Me and John work together, therefore he is my bookie.

(please dont take any of this srsly, its a silly joke!!)
