Peep showA peep show is a form of pornographic performance, where the customers pay to see live performers who are behind a barrier. Each member of the audience has their own window or peephole, usually from within a private cubicle, thus permitting the customer to masturbate.
Visibility through the window or peephole is often restricted by a coin-operated timer mechanism.
The performers (usually female, only occasionally male) may be naked, or perform a striptease. Often, they will seek extra payments from the customers in exchange for them performing particular acts in front of the customer.
"What the butler saw" machines also operated on the same principle, operated by coins. They were also called peep shows .
