Calling someone "sister" is honestly just gay as fuck. I have never seen a straight man in real life call someone else "sister" outside of their own sister; it's genuinely a word that only a stereotypical flamboyant homosexual straight out of Will and Grace would use.

Whenever I see the word "sister" posted onscreen, I cringe on a biological level, knowing that the cock-muncher on the other end of the line has terminal HIV that I might catch through the screen.
