Tickle torture
Tickle torture is the prolonged use of tickling to abuse, dominate, harass, humiliate, or interrogate an individual. While laughter is popularly thought of as a pleasure response, in tickle torture, the one being tickled may laugh whether or not they find the experience pleasant. In a tickling situation, laughter can indicate a panic reflex rather than a pleasure response, and the tickling may be a consensual activity or one that is forced, depending on the circumstances. In a consensual form, tickling may be part of a mutually fulfilling, physically intimate act between partners. However, tickle torture can cause real physical and mental distress in a victim, which is why it has been used as an interrogation method or to simply show dominance over another person. Usually tickling is done on feet and armpits after tying the person's ankles and wrists. The recipient is also often stripped to their underwear.
