Meaning of くれる in 転がってくれるわ


I found the sentence: ようし、転がってくれるわ！ It was translated as: Alright, I'm gonna
roll around! (The context is that the character is rolling on a soft tatami,
he's alone so he's not really talking to anyone, just to himself.)

I know that くれる means to give, but since in this sentence no one is receiving
anything, what is its meaning?




Verb +
[くれる](https://dictionary.goo.ne.jp/word/%E3%81%8F%E3%82%8C%E3%82%8B/#jn-64758)
can mean

> ㋐人が自分に、または自分の側の者に対して何かをすることを表す。「手伝って―・れる」「秘密にしておいて―・れ」「母がセーターを編んで―・れる」
>
> ㋑こちらが、相手に不利益になるようなことを与えることを表す。「痛い目にあわせて―・れるぞ」

Roughly it means the subject does V as favor or as something causing harm to
the listener. In your example, I guess the speaker is just saying either _I
will give you the honor of my rolling around here_ or _I will do harm by
rolling around here_. Not really that these are seriously meant, but more of a
joke.
