pahky
Use pahky when your brain feels like total garbage because you cannot catch a single word someone spits out. It means you are too dumb to care about their boring crap, so just give them the 'meh' of death.
My cousin talked for an hour about cats but I only said pahky since his words were boring trash.
She asked me about my weekend plans and my brain froze so I just threw a quick pahky back at her.
The teacher rambled on the rules but we all groaned with a collective pahky because nobody cared to listen.
