Its used as reassurance to make sure your being compleatly honest. If you sware on the boys and a bro finds out that you lied, your not concidered a true friend. One is never supposed to be dishonest while swaring on the boys, its just something you don't do.

Get the boy boy mug.
Real talk. Serious talk. Usually between adolescent teenage boys. On occasion, "Boy to Boy" talk can be among grown men when trying to get each other's serious attention.
Example: You break your ankle jumping over a girl who you were trying to T bag. You scream to your buddy who is laughing and thinks you are kidding, "DUDE! Boy to Boy! I need to go to the ER!".

Get the boy on boy mug.
A phrase that is used to excuse the natural rowdy behavior of young boys like getting dirty, being hyperactive, and playing rough with other boys. However, it has been disgustingly appropriated by misandrist gender ideologues who have perverted by falsely claiming it is used to excuse criminal activity boys and men do including rape, assault, and murder.

The closest thing to a female equivalent would be a girly girl.
