kid

The term carries a heavy sense of informality and affection. When applied to humans, it strips away the formality of child, often implying a sense of playfulness, innocence, or occasional mischief. It is widely used across various social classes in casual speech but is generally avoided in legal or medical documents. As a verb, it describes a lighthearted deception. It differs from lying because the intent is usually amusement rather than malice. The feeling is one of shared laughter or a playful trick, creating a social bond through a temporary, non-serious falsehood.
