It means go fuck yourself

… and what do gfys mean and I can ignore you but still swearing is not the best thing to do

I have five points.
1: This isn't a game, it's a social media app,
2: you really expect a British cunt like me to be able to resist swearing? You got another thing comin

4: my audience is barely kids, if I even have an audience lmfao
5: gfys 🥰

I can say it if I wanna
