A phrase that is used primarily by the uneducated to skip over the most important details of any given story. Unlike 'yadda yadda yadda', which is usually used to skip over the unimportant details, 'woo woo woo' skips over the most important parts.
Used by the storyteller to minimize guilt, involvement, or responsibility. Often contains incriminating information.
Detective: "Can you explain where you were last night?"
Ne'er-do-well: "Well, I left the house about 5 'cuz my baby momma was all up in my shit, woo woo woo, now she dead."
"I met this fine female at the club, we chillin', sippin' on a little Hennessy, woo woo woo, I'm locked up on some bullshit rape charge."
