When Gaydar Signal is Off.

 "Gaydar" is a slang term that refers to the supposed ability to perceive or recognize someone's sexual orientation, particularly whether someone is gay, based on intuition, behavior, appearance, or other subtle cues. The word is a blend of "gay" and "radar."

While some people believe in the concept of gaydar, research suggests that it is often based on stereotypes and assumptions rather than an actual ability to detect someone's sexuality. It can sometimes lead to misunderstandings or reinforce harmful biases.
