There's an Arab kid at my school named 'Jimi' who always calls me 'cracker' for my un-tanned skin. (I don't tan, I freckle or BURN)
He goes on saying 'you suck, cracker' for a few months. Normally, I would just laugh at him. One day, I was having a bad day and I was just mad. He spits out another derogatory term, and I rudely signal him while saying 'shut the forget up, mother forgeter.'
He doesn't talk anymore. :D
