shift 

To shit whilst fucking. Hence the added "f" to the word "shit".

I was banging Veronica in her ass and when I pulled out she shifted all over me and my mattress. This made me puke and shift myself until the entire room was covered in vomit and shift. So I decided to grab her by the hair and shove her face in the shift that she blew out of her asshole in the first place. What a shift head.
