Facerazzi = Facebook Paparazzi
Someone who goes to parties to shoot photos of people who are drunk/wasted and uploads them to his/her facebook album the next day!
Guy1: Man, I got wasted last night at Gina's party.
Guy2: I know.
Guy1: How is that possible? You were not there.
Guy2: Sam posted the photos today in the morning on his facebook album.
Guy1: Bloody hell! He always does so! Sam is a f*****g Facerazzi!
