gaydar 

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!)

My gaydar went off as a man in tight leather pants walked by.

I've got a good gaydar. He's setting off my gaydar. My gaydar is on code red right now. She's got an overactive gaydar; she thinks everybody is gay.

gaydar 

A radar detecting the homosexuality of someone or something. Gaydars are not physical devices, rather a small part of the brain used to factor characterisitcs such as voice, actions, excitement and tightness of pantwear together to get a gayreading. gaydars also do not measure any kind of speed, so don't be an idiot and see how fast you can pitch a baseball with it, or you'll lose it.

So you guys, does derek really walk the other side of the sidewalk?
Well, my gaydar on him is through the roof.

I hear Jane bats for the other team.

Tellitubies have the worlds highest possible gaydar.
