What does っか mean after the imperative form?


I was watching Chainsaw Man and found these sentences.

> 動け **っか**?

Or the second sentence below:

Person 1:

> 殺すのはもったいない顔だけど、死んでちょうだい

Person 2:

> 胸を揉む前に死ね **っかよ**




"動けるか？" is formal but in spooken language it sometimes change to "動けっか". In
this case る became very short so "動けっか". I never speak like this but Son-Goku
in Dragon Ball speaks like this. And "死ねるかよ" is also formal too.
