I swear to god, I'll fill your sinuses with urine.
A wild promise you make when someone is giving you grief or you want them to back off. Like if your best friend won't stop bugging you about your crush and you're done with it.
My best friend won't stop asking about my crush. I swear to god, I'll fill your sinuses with urine.
My little brother keeps stealing my snacks. I swear to god, I'll fill your sinuses with urine.
My neighbor won't stop yelling at me. I swear to god, I'll fill your sinuses with urine.
