short for Facebook rape
The act of raping someone's Facebook profile when they've left their computer or device unattended and their account signed in. Profile pictures, sexuality and interests are commonly changed, however fraping can also include the poking or messaging of strangers from someone else's Facebook account.
In other words it's when a person leaves their desktop/laptop/device unattended whilst signed into Facebook and someone goes into their account and changes parts of their personal page to humiliating or undesirable material. For example, "Dude, did you see Jonny's Facebook profile, someone fraped him big time."
