Jackie Offy - A fancy lie kids tell to make it sound like they know what a

A fancy lie kids tell to make it sound like they know what adults are doing in the bathroom, even though they don’t.

I told my friend it was 'Jackie Offy' and now I have to pretend I know what that means.

My brother said 'Jackie Offy' in front of my mom and now he’s grounded.

I used 'Jackie Offy' in a text and my friend called me a fake.
