An excellent way of referring to somebody who has angered you.
That stupid fucker pissed me off!
someone who is just in it for a one night stand -- even when the other person is rich, beautiful, loves them and is ready to have children with them even if they have to hide it from the public.
Particularly someone who intentionally gets drunk to commit such one night stands after long plans to set up the opportunity.
I banged Paris Hilton then pushed her out of the car into the mud after she asked me to marry her. Boy I am a stupid fucker or what?
I stole Brad Pitt from his wife that night then ran away when he offered me her ring. I guess I am a pretty stupid fucker.
