I have no idea what the down low means. Please explain.
“Down Low” is a homosexual or bisexual who doesn’t want it widely known.
On the down-low, or on the DL, refers to information that’s kept quiet or under wraps. It emerges in Black slang by the 1990s. Both down and low underscore the slang’s sense of “quiet” and “hushed.” Since at least the early 2000s, down-low refers to men who secretly have sex (on the down low) with other men.
