Angelo:"Maria, my gaydar has not gone off, so no, he's not gay. Trust me."
Maria:"Thanks Angelo. I knew that you'd tell me if my new crush really liked men more than he wanted to let on."
Angelo:"No biggie. What good is having gaydar if I can't use it to help my best girlfriend?"
It's like Spiderman and his Spider sense. He can just "feel" when there is danger nearby. Gaydar allows you to "feel" when there is gayness nearby.
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)
