Everywhere I go I hear children use that word "ojuju calabar will catch me" especially when it involves darkness or when there's no light:

I wonder who teach them such language

Imagine an igbo child or yoruba pikin shouting ojuju calabar hahahahha

Who teach am say na masquerade?

Because ojuju is another name for masqurade and calabar people like masqurades. wheneva kids find themselves in the dark, they always thnk calabar ojuju is coming to get them.

I said that a lot as a child. Ojuju calabar Ayaya oo

Ojuju calabar
oyonma oyonma.
We used the word too,in hide and seek play.

Ojuju calabar was a bully at my school.
