Pookie has long been used online as a playful pet name for a partner, close friend or favourite character, and the stretched spelling pookieeeeeee mirrors how people type the word when they are excited. Short voice clips built around a single repeated nickname spread easily on soundboards and in short-form video because they need no context to understand. This version stays popular for its timing, arriving as a quick two-second burst that editors can drop into captions, comments and edits without explaining the joke or setting up a scene beforehand.
