Mother of Fuck 

Expletive. An expression of awe and appreciation. From the blending of "Mother of God" and "mother fuck."

"Mother of Fuck, what a sweet ass."
"Mother of Fuck, you were hot last night."

Mother of Fuck. 

The moment you're hit with the supernova of a personalized special kind of "fuck you" to top your life's cake with.

Mother of Fuck. It's not something you say. It's what happens to you.

Mother of fuck 

Basically, this phrase is the same thing as "motherfucker", but I invented it. I basically use this phrase when I'm pissed off. Either that or "God fuck!" So, yes. Use wisely, kids.

"Mother of fuck! I can't get a mother of fucking "A" on my test!"
*Literal example* "Mother of fuck! Why can't I make any {basketball} shots?!"
