I could never imagine a gay man saying "sis" to another man in real life, it would be awkward if you said it to a straight friend.

It's just slang. Not only atrl, even one of the biggest forum with many homophoebes in my country (and a lot of straight people on Internet) use a word which has the same meaning

Harry is trolling again

"sis" just sounds really funny imo

.

More like scary

I don't know but it sounds horrible.

It's so I say bruh instead

It is, I always laughs when it's used in an insult.

I can't at Alexz even calling it iconic atm.

I only say sis on ATRL. I say "gorl" with as much emphasis on the O as I can in real life, but that's only to people who are actually girls.

Student information system, At least that's what i think it means
