motherfucker 

One who fucks his or her own mother. However, in recent times, it has adapted to:

1.) One who fucks any mother (which means your father/mother's girlfriend is a motherfucker).

2.) An adaptable insult for anyone whom you'd like to offend.

1.) "Johnny, you're such an incestuous pig, you motherfucker!"

2.) "Your father is such a motherfucker."

3.) "Billy, you haven't showered AGAIN, you motherfucker?!"

motherfuckingniggerass 

Thine definition of the motherfuckingniggerass started once upon a time, long, long ago when a black ass nigger bitch named obama Binladen was being a typical nigger, being all cocky and shit all the fucking time, just like straight up niggers such as sir mcniggins. Anyways, this motherfucker obama Binladen went and performed a nigger car wash on this sexy bitch named Oprah Winfrey. Fuckin niggers. But then they found out she owns a fucking Nigger Car. So she's a piece of shit too. Except obama Binladen is still a motherfuckingniggerass.
