Basically an extension of the word "fuck" but with a little more edge and conviction. Back then, it did have something to do with an individuals
mother but today, people use it loosely i.e. movie dialogue,
music, art/graffiti and it has nothing to do with anybodies
mother. It may have started as an expression in most African-American communities but it has become one of the most universal words on earth.

Person on the street: "Hey you bitch ass motherfucker, I got you!"
