The setting is 4 kids in a park in Japan. The kid sitting on the bench is
Ageru-kun, who is uploading a video to the internet, which is illegal in
Japan. His 3 friends go up to him and have the following conversation.

> あげるくん遊ばないの？  
>  Aren't you going to play, Ageru-kun?
>
> 昨日の番組をネットに上げてから  
>  Ageru: I'm uploading yesterday's program to the internet
>
> またかー  
>  Friend A: This again?/ Not this again!/ Oh, not again! (Not sure which one
> exactly)
>
> 暇か  
>  Friend B: spare time; free time; leisure (Not sure which one exactly)
>
> 見られなかった人のために上げているんだよ  
>  Ageru: I'm uploading it for those who couldn't see it

question
grammar meaning sentence
If somebody just says "暇か", what does that mean exactly?
This could be pretty loosely translated something like "You got nothin' to
do?" or " _Somebody's_ got a lot of free time," said in a sarcastic manner.
Thus, I'd say it would fall under the "spare/free time" category.

answer
「[insert a single noun/na-adj.]か！」 ( _exclusively with a falling intonation_ )
is a quite viral slang/meme template for a while, where they find useful to
tell roughly the following emotions with as terse as one extra syllable
overhead:

  * "Come on! Why are you so --?"
  * "What a (f-ing) -- are you?"
  * "Like it's such a --, huh?"

I believe this construction originated from the comedian group タカアンドトシ's
signature joke, most well-known in a fixed phrase 欧米か！ "As if (you're in) the
West!" (which is said by トシ (straight guy) after タカ (funny guy) plays
something stereotypically Western drama). Due to its versatile simplicity, it
quickly gained popularity that now I almost hear it once a day on Twitter or
reality. The choice of word before か is crucial in this pattern.

Though it's partially true that this usage can be explained as an original
sense of particle か, I remember we usually needed to phrase ～かってんだ, ～じゃん（かよ）,
or ～なのかよ for similar connotation before the meme. Also, this type of か is only
grammatical after a noun or na-adjective in theory, but recently I start to
see something like [かわいいかよ](https://note.mu/marketing/n/nee1a23dc44e7) which
is an obvious anacoluthon but IMO very effective.
