If it's done to cause hurt or embarrassment, then yes, it's offensive and bullying.
It doesn't matter if the person is gay or not. That makes no difference to the offence.
Calling someone gay as a term of abuse is offensive and illegal in many countries. Bullying and cyberbullying similarly.
It is two words really. The whole thing is a phrase calling someone the lord of gay which is offensive to gay people.
No, however, attempting to insult someone by calling them gay is ignorant.
no
Nope!
It can be, but it depends on the manner in which it's used.
It depends entirely on the context. If a person identifies as gay, then calling them gay is not offensive. In fact, it is infinitely preferable to call them queer, homo, fairy, sissy, etc. However, it is offensive to use gay as a pejorative (e.g. "I hate that guy, he's so gay,") or to use gay as an all-purpose word for something bad (e.g. "Wow, that stupid show was gay").
say that's not what your mom said last night.
no, it's sexual orientation discrimination. Racism is discrimination for different races.
Just say this: That's not what your mom said, It Takes One to Know One,, Yeah im the gay one you keep on calling me gay that means you think about guys to much.
If it is done sevaral times then yes, if its just once then its not bullying, its just pointless.
It is offensive. It means you are gay (but it uses a very offensive term for "gay")
