I'll fuck you faggot.
You're not just being called a faggot. You're being told you're gonna be stuck with that person for life. No way out. No hope.
My dad said, 'I'll fuck you faggot if you don't stop being annoying.'
My friend said, 'I'll fuck you faggot if you don't stop talking to me.'
At school, my teacher said, 'I'll fuck you faggot if you don't stop being loud.'
