(Derived from the English term "oops", but carrying a heavy slur. Used in a sarcastic manner for comedic relief under ironic circumstances)
The adoption of the slur refers to a Dateline's To Catch A Predator episode where the Predator is caught again. You can view the video and find the Oop'sh reference by searching the term:
"Dateline: To Catch a Sex Predator... Busted AGAIN!! "
AA: Ugh. I tried to let a SBD (Silent But DEADLY) out during the meeting, but farted out loud by accident!
