Osuwari

is a running gag in the series that has Kagome Higurashi saying a varying phrase that ends in Inuyasha falling flat on his face. There are many times in which she abuses this power such as when Inuyasha is annoying her or she doesn't feel like talking to him. Kagome got this power after Kaede placed a necklace on Inuyasha that gave control over him to Kagome. When Kaede asked Kagome to say a word that may bond Inuyasha, she says sit boy as she notices Inuyasha's cute dog ears. Others have tried to tell Inuyasha to sit but have failed to get the same results because Kagome is the only one who can control him as such.

This played a vital role in Inuyasha's development, keeping him from harming Kagome (as, being part demon, he is unable to remove the necklace) and eventually growing fond of and wanting to protect her and others as well. Throughout the whole Inuyasha series including the movies, Kagome has said "sit" a total of 148 times.

Examples

 * Kagome and the gang are waiting for Inuyasha to end his conversation with Kikyō and when he gets back, Kagome becomes frustrated by his unwillingness to talk and repeatedly says "Sit, boy!" until he is implanted in the ground.
 * Inuyasha is picking on Shippō and Kagome yells "Inuyasha, sit boy!" and he falls flat on his face.
 * Usually whenever Inuyasha gets into fights with Kōga, Kagome makes him "sit", in order to get the Wolf-demon to leave faster and stop them from possibly killing each other.
 * Kagome is upset with Inuyasha and has decided to not talk to him. Inuyasha, determined to get a response from her keeps egging her on and in retaliation of this annoyance yells for him to sit which makes him once again fall on his face.
 * Inuyasha and Kagome are going back and forth over whether or not Kagome is crying and she tells him to just 'shut up and sit'.
 * Inuyasha is unknowingly being rude or saying something that might offend someone else and Kagome tells him to sit to get him to be quiet.
 * Kagome accidentally said sit in the middle of a conversation with the rest of the gang, but Inuyasha still "sits". Also in the 3rd movie, Kagome accidentally says it when claiming that she doesn't say it that often.
 * Inuyasha comes to Kagome's world while she is sleeping. In her dream she tell him to "sit", which also takes effect in real life.

Trivia

 * In InuYasha the Movie: The Castle Beyond the Looking Glass and InuYasha the Movie: Swords of an Honorable Ruler, Kagome uses the "Sit Boy!" command in such a way that it saves his life (it pulls him to the ground before he is struck by a move that he couldn't have dodged otherwise). It is the first time that the spell (that usually puts Inuyasha in pain) is used to save his life.
 * There have been instances in which Kagome was able to activate the "sit!" command using the word "stupid" (Japanese version only).
 * In the episode "The Lucky, but Two-Timing Scoundrel", Sango told Inuyasha to sit, but failed. She then takes note that it only works with Kagome and Inuyasha remarks, "You just got that, idiot?" (although he was startled when she said it). Miroku, somewhat surprised, thinks to himself, "I was kind of hoping that would work."
 * In Inuyasha the Movie 2: The Castle Beyond the Looking Glass, Kagome was able to apply her "Sit" command to a group of dogs when she felt annoyed by their constant barking, in which they obeyed (albeit fearfully).
 * In Inuyasha the Movie 3: Swords of an Honorable Ruler, during the last scene of the movie after the credits, she purposely says "sit boy" in an soft gentle tone, making it one of the few times when she didn't get angry or annoyed with him.
 * In Episode 100, Inuyasha told/dared Kagome to say the "sit" command.
 * The "sit" command is one of Inuyasha's biggest fears (since he usually stops at whatever he's doing, and looks at Kagome with a startled face), however that still never stopped him from acting out.
 * Counting from the anime, to Final Act, as well as the 4 Movies, Kagome has said Sit/Sit Boy 148 times.
 * Inuyasha was shown to resist multiple "Sit" command in episode 11 (while holding a boulder), until he finally collapsed.
 * Several characters have noted Kagome to be very scary at those moment, some are even shown cowering in fear.
 * "Sit, Boy!" is usually and likely spoken in the English dub for lip synchronization purposes. Kagome usually says only the word "Sit!" at the moment she is off screen.
