Zombie Talk

Calling a person early in the morning after you've just woke up and talking in a half sleep voice.

Calling a person and waking that person up counts as well.

(you-groggy and sleepy) "Heyyyyyy-whu whu when's da parttee?"
(other end) "Dear God don't Zombie Talk me! Go back to bed.
(you) "ruh huh? Okay goodbuh" *ZZZZZzzz*
