A Californian man accused of biting off his wife's bottom lip after she called him short has rejected a plea offer and will stand trial next month, prosecutors said. The man told police he was provoked by his wife attacking him first and calling him a short man, according to the District Attorney's office. Police said Nzerem shoved aside his daughter when she tried to intervene in the argument. He then allegedly grabbed his wife in a bear hug and bit off her lip. Police recovered the lip from the floor but doctors were unable to reattach it. The man's wife said authorities had exaggerated the extent of her injuries. He is facing misdemeanour charges of child endangerment and violating a court order, said Steve Wagstaffe, chief deputy district attorney.
