Similar to Spidermans Spidey-sense, except where Spiderman's spidey-sense detects imminent danger, a gaydar detects a homosexual nearby, either thru hearing the tone of one's voice or observing the style of their movement, which sets off the realization that this person may prefer members of the same sex. (Being a homosexual, deal with the definition, because most should defend this one!)
