Nah dat'
You're saying ‘fuck no’ so loud it could wake the dead. It’s like you’re tired of hearing the same stupid idea again.
Nah dat', that idea is so dumb I could’ve been a millionaire by now.
Nah dat', you just said something so stupid I can’t even believe you said it.
Nah dat', that was the worst idea I’ve heard since my mom tried to make a cake out of glue.
