I'll fuck you faggot.
It's not just a swear. It's a promise. A promise that you're gonna be stuck with that guy forever. No escape. No mercy.
My dad said, 'I'll fuck you faggot if you don't stop crying.'
My friend texted me, 'I'll fuck you faggot if you don't beat me up.'
At the gym, the guy said, 'I'll fuck you faggot if you don't lift more weight.'
