"It measures gayness. With science."
—Doctor Insano, The Spoony Experiment
The ability to determine a person's sexual orientation without being explicitly told — or rather, the ability to detect gay people who haven't outed themselves to you. This may require anything from a casual glance, to hearing the target speak, to near-constant observation. In theory, a gaydar would detect straight people as well by process of elimination. In reality, the sheer amount of things people can be beside just "gay" vs. "straight" means no one's gaydar is perfect.
Can be confounded by the presence of a Camp Straight, but not always. Much depends on how much the gaydar depends on gay stereotypes.
Can also rely heavily on an observer's common wisdom and intuition based on life experience, with good gaydar being measured by its probability of success, making this Truth in Television. (Compare Transparent Closet for gaydar's easiest detections.)
The term is a combination of the words "gay" and "radar".
This trope can be very close to LGBT Fanbase, especially where an observer likes what they see, is using Shipping Goggles, or otherwise is practicing some form of wishful thinking. But just as often, Gaydar can be perfectly sincere audience interpretation, whether or not there is also LGBT Fanbase — use caution when calling Fan Yay on someone's Gaydar.

Anime & Manga

Comic Books
- Y: The Last Man: Dr Mann mentions that an old colleague of Agent 355's reminds her of an ex. When Yorick asks "She reminds you of an ex-boyfriend?", Dr Mann points out that's not what she said. One Beat Panel later, Yorick expresses disbelief at how he's been traveling with her for a year without realising, and she snarks that they can add gaydar to the other common senses he seems to lack. Although that said, the whole Gendercide thing and its logical consequences would play hell with even the most finely-tuned gaydar.

- On The Simpsons, Homer is tasked by Marge with finding a potential suitor for either Patty or Selma. When he assesses Principal Skinner, he notes, "Possible Homer Sexual."
- It's implied in The Owl House episode "Wing it Like Witches" that Willow has picked up on the fact that Amity is in love with Luz (something that no one else shows any signs of suspecting until the following season). The fact that she's the daughter of a gay couple probably helps.
- One episode of Lastman has Richard "guarding" a mobster's daughter on her way to meet her arranged husband. Problem is she's a lesbian who, understandably, doesn't want to be married to a man. At one point, she tells Richard that gay people can just tell when someone else is gay just by looking at them. When she and her future fiance finally meet, we see their respective gaydars going off towards each other (with one big lit up arrow pointing at her from his perspective and a bunch of lit up arrows pointing at him from her perspective). Suddenly, it becomes clear her father was actually setting up a Marriage of Convenience that both can agree to—which may have been what he has with his wife.
Real Life
- Relatedly, there's the "transdar". It's mostly related to whether a person "passes" or not, or how they behave pre-transition. It can be easy for out trans people to spot closeted ones — common signs include an obsession with gender transformation, excessive daydreaming, being really really really into yaoi (for female-assigned folks) or yuri (male-assigned folks), crossplaying at every opportunity, and having a whole lot of trans friends.
- There's the suggestion that the greater exposure and acceptance of gay people in society increases the odds of a person correctly identifying someone who is gay because of the acceptance that gay people actually exist and don't all look like drag queens. People from a less open culture (or an older generation) are less likely to recognize someone as being gay because it's hard to recognize something that you refuse to accept.
- A 2005 study had discovered that people can smell people's sexual orientation by body odor. For homosexual male participants, there was a consistent preference for homosexual males over heterosexual males or homosexual females, under the forced-choice paradigm. This suggests that smell is one way of how the gaydar could work.
