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。
