I'm going to call a friend a slut
Is slut a new slang out there now or is it because she is a real slutty girl?
No, there's no way I'll call someone a slut just because of what they do personally.
Calling your friend a name seems to not bother you. This name calling is something that makes everyone feel bad, you need to quit being so complacent about it. Her feelings matter and she will dump you soon if you still think it's right.
I'm a boy and she is a girl so it is normal to call someone a slut.
It is actually not normal to call someone a slut. It is disrespectful to do so.
