A slipper, also called houseshoe, is a soft and lightweight indoor type of footwear.
Slippers may be shaped like a shoe (foot inserted through top), or may have no heel, so the foot can be slipped in the back.
The term "slipper" is sometimes used interchangeably with the terms flip-flop and sandal. This is especially true where footwear is not customarily worn indoors; in Hawaii the word "slipper" generally refers to the flip-flop.
Certain breeds of dog have been identified for their superior ability to fetch their owner's slippers, a domestic version of the fetching of shot prey for which hunting dogs have actually been bred by humans.
It is a form of physical punishment, mainly for children at home or at school, as a milder alternative to caning, birching etcetera, though a 'sound dose' can be more painful then it seems, especially if the impacting sole is solid rubber, a material also used for type of paddle or bludgeon. It has also been applied as an informal military spanking by a soldier's comrades, notably in France under the name Savate (meaning footwear, homonymous with French kickboxing).
The analogous word booting (also irrespective of the type of footwear) is rather used for physical discipline given 'hands free' with the boot (or other footwear) on the discipliners foot, so the punishee usually is to submit to the punishment (generally on the posterior) in a low position. The humilitation is still increased if (s)he must do so over the knee, on all four, kneeling or crawling, or by wearing demeaning dress, only underwear or even bare-butt.
Feeling the boots of the lined-up crew has also been used as a naval variation of running the gauntlet, less painful then a whipping (on the back, e.g. with knotted cords) but rather more humiliating.
