wasabi steamer
The Wasabi Steamer is a close-cousin to the Cleveland Steamer, but with a specific location and additional act. The Wasabi Steamer must be performed in a sushi bar. There must also be a generous application of wasabi paste directly to the anus of the performer prior to laying down the steamer.
When you visit Japan don't expect to see many Wasabi Steamers. They are reserved for very special occasions.
