p'shall
You say 'p'shall' when someone is lying and you're too lazy to call them out. It’s like a hand flip and a ‘whatever’ rolled into one.
'P'shall?' I said, flipping my hand. 'You said you’d clean your room. It's still a pigsty.'
She did the p'shall. 'Whatever. You’re still getting the last slice.'
He did the p'shall. 'You’re telling me you lied to your mom and still think you're the best?'
