A condition exhibited by high school freshmen that add everyone in their school on Facebook with intent of appearing "popular" or friendly with upperclassmen. Commonly abbreviated as "FFS."
Senior 1: Dude, who is this random freshman that added me on Facebook?

Senior 2: I don't know, man! Some of these kids have come down with a real bad case of Freshman Facebook Syndrome!

Senior 1: Yeah, no shit! This kid is, like, 12 and he has 1528 friends!
