Sukuna was saying random shet you'd hear when a Villian is about to die like "No, stop!...". Yuji asked Sukuna if he wanted to live with him but Sukuna said no.

Yuji: "Look, Fushiguro! It's POU-KUNA! HAHAHAHA- Get it?!"

Megumi:"Yuji..are you f*cking kidding me?!"

Poukuna:"Fushiguro.. Now, what do you say if you became my vessel, again-"
