Putrid Child

A nickname/insult for a friend/enemy. Can be used sarcastically or seriously and can be a good or bad thing. They person does not actually need to be putrid or a child for you to say this to them. Actually works best when they're older than you and clean. Can often be compared to calling to someone a scurvy dog
