Gay indicators

Hey guys, so I'm recently out and now that I'm able to talk to my friends about all this, the subject of what indicates a gay guy has come up. There are the obvious ones like makeup, dyed hair, and certain vocal tones. I have argued that eyebrows could also be an indicator, since gay guys are more likely to get them waxed or trimmed. Do you guys agree with me? Is it a valid indicator, and if not, what else could we be looking for?
