Whisper is a mobile app which allows its users to post anonymous messages (called "Whispers") out into the ether and receive replies from other users who might be interested in what they have to say. The messages are text superimposed over a (presumably) related photo to illustrate the point.
A recent update allowed Whispers to be categorized into a few firm subcategories: Confessions, LGBTQ, NSFW, Q&A, Faith and Military. Military members and those with an interest in the military can "anonymously" (quotes because the app still tracks users with their phone's GPS) post their thoughts, feelings, and interactions with military members. For better or for worse, we compiled some of the more colorful Whispers.
Everyone who enlists knows exactly what it will be like for six years. Sack up, military men!
