Common among the socially awkward. Used to describe that REALLY annoying person that frequently tries to brag about having "friends" that have meaningless accomplishments in the hopes of jumping into group conversations. These "friends," more often than not, are people no one in the group can relate to, and are rarely related to the subject. Often results in NOGAF silence.
Person 1: Hahaha! Dude, you look like Napoleon Dynamite when you try to shuffle!
Person 2: Yeah! You have the 'fro and everything xD
Person 3: Ha! PLEEAASE! Neither of you have seen me do the Spongebob huh?
Person 1:*quietly* Phuck! Friendsociator at 3 o'clock!
Friendsociator: I have a friend that knows how to draw Sponge Bob from memory!!
