A fictitious babysitter, created by amoral, trashy, and promiscuous single mothers in order to deflect blame for poor parenting. "Zanny", actually is the street name for a drug called Alprazolam.
I was so bombed, high, and too busy having sex! It sure is a good thing Zanny the Nanny was watching my child!
When you're relatively intoxicated on Alprazolam (Xanax) and require a care-taker(sort of like the fake babysitter mention in the Casey Anthony trial). This is due to the drooling, i know your sister, and baby-rage.
Hey look at this jackass over here all incoherent and shit, someone come get Babysitter Zanny.
