Friendsest 

The (potentially dangerous) act of dating within one's immediate circle of friends.

When a closed circle of friends draws closer and closer, eventually resulting in a group supernova or singularity.

When Catie and Brandon started dating, and the group's friendsest had reached critical mass, no one was sure if a fight or an orgy would break out.

Inflated Friendlist 

When a person on Facebook has hundreds, even thousands, of people on their friend list just to seem 'cool' to their peers. None of these people actually know or may have little contact/interaction with the person sending the friend request. The person sending the friend request think it is cool to have 2000/3000 friends on Facebook, but they never actually like any of their updates because they honestly don't care about the requester.

Aaron: Look at how many friends Kathrine has!
Javier: Yeah, but no one has liked any of her 10 post in the last hour.
Aaron: You're right, she just has an inflated friendlist
