A ball gag is a sex toy,usually made of rubber or silicone with leather straps. Ball gags are used in many ways for bedroom pleaasure, mild bondage and BDSM activities, but they have been observed in the media, especially in a humorous or bizarre context. Hostel, Pulp Fiction, Scary Movie and Candyman 3 contain ball gag scenes, and they have been observed at least twice in The Simpsons, and have even been featured in a video game, True Crime: Streets of L.A.. In use, the ball is strapped into the mouth behind the teeth, with the straps going around the head to secure it in place. If the ball is very large, it may be difficult to push it into place behind the teeth, or to remove it.
