quantum FBchat superposition 

The random mysterious phenomena of two Facebook chat indicators for the same person that are contradictory, suggesting that the person represented is both online and simultaneously offline.
Based on the quantum phenomena where a particle is in both one configuration or state and another configuration or different state at the same time.

Bob: "Hey, is Nina online? Can we chat with her?"
Tim *staring intently at screen*: "Yeah, she is & isn't."
Bob: "WTF?"
Tim: "Nina's subatomic particles are stuck in both the online and offline quantum states! quantum FBchat superposition, dude."
