My indiscreet friend has a habit of blurting out pretty much everything, including all of the secrets she is not supposed to tell.

An indiscreet assassin will simply attack their target directly, rather than bother with cunning or moving in the shadows.

You are likely ill-suited to be a secret agent if you are indiscreet and do not know how to act with caution.

A rhino is an indiscreet animal that lumbers about with impunity and a lack of concern for anything subtle.

You shouldn’t trust someone who is indiscreet with your secrets, as they likely will not keep them to themselves.
