eat my ass with that weak shit
When someone says something so weak it feels like your brain is melting, and you just yell at them for no reason.
My cousin said he can time-travel. I told him to eat my ass with that weak shit.
My dad said he can talk to aliens. I told him to eat my ass with that weak shit.
My neighbor said his goldfish is a philosopher. I said, 'Eat my ass with that weak shit!'
