鸡霸损友
[jī bà sŭn yŏu]
A playful and rather crude nickname that implies someone is a very confident or domineering 'bad influence' friend. It's often used jokingly with friends to describe someone who is bold, perhaps overly so, and mischievous. '鸡霸' can be thought of as a cocky person, and '损友' refers to a 'harmful friend', in a teasing manner.
