This is a very strong way to ask a question. You use it when you are very surprised or upset. It sounds rough, like something a man might say.
今から全部やり直すのかよ！
Are you serious?! We have to redo everything from now?!
あいつ、結局来なかったのかよ…。
So that guy didn't even come in the end?! Unbelievable...
こんなに高いのかよ！冗談だろ！
It's this expensive?! You've got to be kidding me!
犯人、お前だったのかよ！
The culprit was you all along?! I can't believe it!
「また負けたのかよ」と彼は悔しそうに呟いた。
We lost again?!' he muttered in frustration.
This phrase is like saying, "Wait, really?" or "No way!" in English. You use it when you hear something surprising. It shows you feel shocked or upset. It is not a real question. You do not expect an answer.
This is much stronger than "~no ka." "~no ka" just asks a question. "~no ka yo" shows you are very surprised. Or you do not believe something. Or you are blaming someone. The "yo" makes it sound very firm. It is more aggressive than "~kai." "~kai" is also casual. But it sounds softer.
Use this when you want to strongly question what someone said. It shows you are surprised or do not believe them. It can sound very rough. Only use it with close friends.
