These are two people that upon first interaction have an erie mental connection. This includes but is not limited to constantly reading the others person's mind, finishing sentences, sharing unspoken thoughts, jinxing, and laughing upon eye contact because they are both thinking the same thing. A brain twin knows how the other brain twin feels about most all people and topics. This is because brain twins think exactly the same way. Brain twins get along famously and develop close relationships. Other people will often feel like left out when brain twins get together. People may have more than one brain twin although it is extremely rare. Side note: Although not determinative, sexual feelings/tension are likely to develop with co-ed brain twins, due to the egocentric nature of humans.

They would snap in half when you did them
Lindsay Lohan And Hilary Duff are streets ahead of them
