Intentionally getting someone in trouble by outting something they've done wrong while trying to keep it sly.

To indirectly tell secrets or offenses to a person of authority or any person meant to be kept away from a secret or offense, sometimes inadvertently.
If the telling of secrets or offenses is purposeful, minute details are usually left out as not to appear to be directly telling.

It is indirectly snitching.

"I see this offensive picture is still up. I recall other member's being banned for posting such a thing."

Dry snitching is a calculated but yet passive aggressive way to dime out your homeboy. In most cases to save your own ass without being the obvious rat bastard you are and save yourself from a fishing trip in your new concrete Nike’s.

A technique of snitching by indirectly informing authority figures of another person's wrong doing, while not being associated with offense or obtaining any legal gain.

Verb. The proper definition is to ACCIDENTALLY or UNINTENTIONALLY snitch on yourself or someone else.

Indirectly telling an authority figure or interested person who might have been involved in the incident the authority figure or interested person is curious about. It's not "pointing the finger" but more or less telling them as if they already know or as if they are clue less.

To explain how something works that, by nature, is not supposed to be explained but rather understood or experienced. A practice most commonly used in a number of rap lyrics. Basically tellin on yourself and others while trying to show out or look cool.
