1. jovial or happy, good-spirited

2. a homosexual male or female

3. often used to describe something stupid or unfortunate. originating from homophobia. quite preferable among many teenage males in order to buff up their "masculinity"

1. Happy.
2. Homosexual.
3. A generic insult.

1.The dictionary definition is happy. However, this is archaic and few people use it any more except in the phrase gay old time.

2.Homosexual, especially homosexual males but can be used for lesbians as well.

3.A generic insult. It can mean bad, stupid, whatever you want it to mean.

My Opinion:

Don't say that something is gay as an insult. I find this highly immature, mostly because it is often used when people can't think of a proper insult even when there is nothing homosexual about whatever they're insulting.

Originally meant joyful, vibrant, and full of life.

Now it's used by ignorant (and often prejudiced) people to describe something that they don't like. It's especially common among teenage boys, who use it to look cool or to "hide" their insecurity about gay people.

Gay is now slang for a homosexual person, that is, somebody who is attracted romantically and sexually to people of their own sex.

Gay men are known as gays, while gay women are known as lesbians. And some bisexuals also identify as gay.
Up to 1 in every 10 adults is predominantly gay; everybody is somewhere in between the two extremes of heterosexual and homosexual.

Gay is only sometimes, but not always:
-Living with AIDS.
-Living a promiscuous life. ...

sexual attraction to one of the same sex.

1. Attracted to the same sex, and ONLY the same sex.

2. A word immature assholes use to describe anything that sucks, without regard to its actual sexuality.

Disclaimer: I am straight, but I do try to be mature most of the time.

happy. joyful. gleeful.
