gaydar 

The amazing ability to sense gay or bi (tho mostly the first) by apperence, personality, how they talk, move breathe, practically how they sleep.

Usually the gay/bi ones are always the good looking ones. ie: Nick Lachey, David Beckham, Channing Tatum, Ryan Carnes, Chad Michael Murray

and usually the ugly one's are hetero.
ie: Dick Chaney, George Bush and Bill O Reily (sad isn't it)

Kate: This guy Dave is like a total hottie!
Jeff: Dave? he's gay, my gaydar pinged when i saw him
Kate: ohh thats too bad. who else is gay?
Jeff: Your husband
Kate: Noooo you lie you fag!
Jeff: I slept with him so take that you fat bitch!

Gaydar 

A persons ability to ACCURATELY tell if people around them are actually homosexual. Without asking the suspect or anyone who knows them directly or indirectly.

Person of "happier" inclination walks into a bar in a backwater, where incest is the norm but gays are burned at the post and manages to get laid with a local of the same sex from said bar would be said to have good gaydar and some pretty good moves!

Noun,

1. The uncanny ability or supernatural power possessed by most gay men, lesbians and fag hags to detect gayness in others. Is highly effective, especially if the object is in the near vicinity.

2. An imaginary internal machine that registers and detects radiated gayness. A gay-o-meter.

3. An obnoxious but addictive website for gay men to post personals and pictures, hook up with others and diss anyone who isn't a Chelsea queen or gym bunny.

1. Sam says he's straight, but my gaydar tells me otherwise.

2. The cute new temp at work is setting off my gaydar.

3. Man1: How was your date last night?
Man2: Awful. He didn't look anything like his Gaydar pictures.
