Obb! 

That moment when two people say(or think) the exact same thing at the exact same moment, but one person says it first. Then the other person should say "Obb!"

Use this when both of you have been completing each other's sentences so much, that it becomes 'obvious' that the other person must also be thinking the same no matter how random the thought might be.

This word shortens the conversation from "Heyy I was thinking the same thing. Obviously." to just "Obb!".

* A stranger passes by *
* person1 and person2 think of a party they attended *
person1: Heyy this guy just reminded me of that party we had 110 years ago.
person2: Heyy!! Yeaaa!! Obb!
