A sacred vow that transcends all fake promising rules (ex: crossing fingers). This is a serious deal that is of the upmost importance.
Guy 1: Hey bro, pinky promise me you won’t tell anyone who I like.

Guy 2: Yeah bro of course.

Guy 2 will be sacrificed to the pinky promise gods if breaks this sacred agreement.
