Every time I hear someone say fam I want to rip their hair out. I have literally never heard someone use that when speaking to an actual family member.
Hmmmmmm. My mom would laugh in my face (and rightfully so, in my opinion) if I ever said that. It just sounds disrespectfully casual in every setting I've heard it used.
"Fam" implies a close relationship. You're supposed to use it on close friends a friend you count as family. It's just an alternative for bff or whatthehellever. Btw I fucking love yo name
"For real fam"
tldr
