A Brown nose

Maybe, if your into that kind of thing. I guess that would depend on how openminded one is.

Some people say they have "Gay-dar" but I don't believe it.
Try asking him if he knows the difference between puce and ecru.

I can sometimes. It's intangible. It's the way gay men and women interact with those around them. I am not 100% by any means, but I can tell on occasion.

Why do you want to know?

If they want you to know, they'll tell you. Otherwise, it's none of your business. Same thing goes for anything else that may be personal.

"Otherwise, it's none of your business."

Well, not exactly. If you're talking about dating situations and your own intention is typical hetero relationship, I think the topic is fair game. People can be deceptive in all kinds of ways and sexual orientation can certainly be one of them. The stories I've heard from my dates (I'm male) over the years have been amazing....along the lines of girl's thinking "maybe husband material" but the guy's actually gay and doesn't fess up until months have gone by. Kind of a waste of time, I think, and can be painful.

Ya, I think one can 'tell' by watching mannerisms, listening to speach patterns and listening to how they relate to you in conversations.

We have had several politicians who have been married for years and finally 'come out' when someone 'finds them out' - I think, in a lot of cases, it takes close scrutiny, but the signs are there and you 'can tell'.

Also, in today's society, it's quite acceptable to 'come out of the closet' and be whom you really are.

I have quite a few Gay friends, so I'm very much aware of the signs.
