Friend Equilibrium 

The point at which one's overall number of friends on Facebook (or other social networking site) Stays at roughly the same number. This phenomenon occurs when one has maintained a profile for a few years, and the rate at which that person is making new friends is equal to the rate at which old friends forget about the person and remove him/her from their friends lists.

Person 1: "That's so weird... I just added Mike and Jane as friends last week, but I'm back to 563 friends again."

Person 2: "Ah, I see you have finally reached friend equilibrium."

Reaching and maintaining a friendship equilibrium where everyone gets along very well with no issues or drama.

Kate: We had a really great friendship equilibrium going on, now that Jordan is back he might ruin it!
Jess: Yes, our friendquilibrium is in danger.
