My Girlfriend was acting up, so i surprised her with a Mexican Hot Poker! Unfortunately while I was fucking her in the ass some hot saucedripped from my balls into my ass and we both went to the ER. So please only use hot sauce as needed.
The defintition of the word litterally means "I Don't Believe it!" or "Holy Crap!" It's simply an exclaimation used to suggest shock. The Phrase comes from the Movie "Live From Baghdad." Thats the only place I've ever heard it used.
This phrase can be taken literally and is often hilarious if people look at you strangely for saying it.
