kabballoh
it's when you say 'holla back' backwards and then someone gets mad because you messed it up.
I said 'kabballoh' and my friend got mad because I messed it up.
He said 'kabballoh' and I said it wrong, and he laughed at me.
She said 'kabballoh' and I messed it up, and I had to redo it 10 times.
