because they like another boy
No, it's not "ok" to call people gay.
Only if the joke is meant to be offensive.
You call people gay if they are attracted to members of the same gender. But it's really better to call people by their names.
I have heard the term, "Bisexual" used, but it may not be precisely the term you want.
Guys pierce their right ear if theyre gay.
You can call it anything you would call any other group of people. Gay men aren't like animals, they don't travel in herds or flocks, it's just a group of people.
because much gay
no. theyre gay
Gay women can also be called lesbians, but the best thing to call them is "women".
they usually call them by their names, but I think the term you're looking for is "gay".
Gay people only follow other gay people.
