1. gay radar
2. The ability to pick out all gay individuals in a crowd
3. The ability to instantly know if someone is gay, like a 6th sense.
This is a handy little intuition to have! Gaydar relies on observation and intuition. If you have good gaydar, you can tell if someone is gay the moment you meet them. BAM! It’s like the same thing that creepy little kid from The 6th Sense has, only instead of sensing dead people, you sense gay people. Wonder what where the gaydar would rate Bruce Willis?
