Tickling Charm

The Tickling Charm is a spell that causes a victim to buckle with laughter. This is usually used as a diversionary tactic in duels, such as when Harry Potter used it on Draco Malfoy in the Duelling Club of their Second year. It is not known how this affects a person who is not ticklish, it may just knock back the opponent. The incantation is Rictusempra.

Etymology
"Rictusempra" is derived from the Latin "rictus," meaning "The expanse of an open mouth" and Latin "semper," meaning "always."

Behind the scenes

 * This is the first incantation Harry Potter has done verbally and with a wand in a film. He used it on his duel against Draco Malfoy in the second film.
 * In the film version of Harry Potter and the Chamber of Secrets, Malfoy is simply knocked backwards. The same occurs in the game version (also in Prisoner of Azkaban and Order of the Phoenix game versions), where it is treated as a minor offensive spell, rather than a tickle charm. The use of it in the film could be because as Harry was an inexperienced wizard at that point, he may not have been able master the spell propely, thus causing a different effect. Also, in the film and video game(s), it is red or pink rather than silver.
 * It can be bought at Wiseacre's Wizarding Equipment in Diagon Alley in LEGO Harry Potter: Years 1-4.
 * Since this charm creates a sensation of being tickled and makes the victim collapse to the ground, this charm can be called a "minor torturing" curse.
 * There is another spell Titillando under the name of the Tickling Hex. It is unknown how they differ. It can presumed that the Tickling Hex would cause a less desirable effect.
