What does 「コロリ、コロリと」 mean?


It's my first time asking a question in this website so I hope I'll be as
clear as possible.

I'm new at learning Japanese and I'm reading a book containing the phrase
「コロリ、コロリと」. It is impossible for me to understand. I tried looking it up on
google but I couldn't find any proper explanation about it.

Could someone please explain it to me? Here's the entire sentence

> マエダさんは、 **コロリ、コロリと** いうところで、うしろを向いてグルグルと首をまわしはじめます。




Native Japanese speaking. It sounds weird to me because we use コロリ in a
situation like

> 「彼はころっと死んでしまった。」 ("He was killed easily.")

or something like that.

And we don't use this word too much. You don't have to care about this because
this usage is incorrect.
