GAAB - A word Elahe uses to insult people. It sounds like a baby’s

A word Elahe uses to insult people. It sounds like a baby’s version of 'cow' and it’s the worst thing to be called.

Elahe said, 'You’re a GAAB and you act like it.'

He called me a GAAB in front of my whole class.

I got a GAAB in the middle of a math test and I failed.
