Unibrain 

When you and another person - typically love interest or close friend - develop the same thought at the same time. Possibly even from different locations; two brains functioning as one.

Person 1: *Hungry, thinking about pizza for dinner*
Person 2: How you feel about Pizza King for dinner?
Person 1: OMG absolutely, unibrain!
