A slippering is a metonymical term for the act of smacking the buttocks, or the hans, with a slipper as a form of corporal punishment. A slippering on the buttocks is a form of spanking; it is a much more common method than slippering on the hands. The verb 'to slipper' means 'to give a slippering'. Slippering is used in three contexts: domestic punishment, school punishment, and erotic spanking. This article is only concerned with domestic and school punishments. There are very little data, research or evidence about the use of slippering. Information is mainly based on anecdotal reports from individuals who have given, received, or observed slipperings, or who have been in households or schools where slipperings were used. Slipperings are particularly associated with Britain and Commonwealth countries, although not exclusively so. In a sense this article is of historical interest only, as slippering is probably approaching extinction.
