Facenize

To recognize a person or people you know only tangentially through Facebook photo albums, including albums of those you don't know, but have access to because friends are tagged.

When I walked out of the restaurant on Ontario Street, I Facenized that dude from that Bonnaroo photo album. I almost said "hi", but I forgot that I don't actually know him.
