What is tickle?

Tickling is the physical act of touching a person's body in a way that causes involuntary laughter or convulsions. It is often performed for amusement or to establish social bonds between people. Tickling is most commonly done on the feet, stomach, and underarms, and can elicit strong physical reactions and laughter. However, tickling can also be unpleasant and uncomfortable for some individuals, particularly those who are hypersensitive to touch or have sensory disorders. In extreme cases, tickling has been used as a form of torture or interrogation. Overall, tickling is a complex and varied phenomenon that can have both positive and negative implications depending on the context and individuals involved.
