dated In the military, any gossip, rumor, or unfounded information passed along in the latrines of soldiers. If the latrine rumors are to be believed, we're going to be relocated to an area outside of Danang next week. You shouldn't believe every latrine rumor you hear, son. When soldiers have too much time on their hands, they start spinning stories.
