It entails an individual who, thinking they're alone, engages in some expressive behavior — wild singing, gyrating dancing, some mild sexual activity — only to discover that, in fact, they are not alone, that there is a person watching and lurking, the discovery of which causes them to immediately cease what they were doing in horror.
Implica a un individu que, pensant-se que està sol, es comporta expressivament — cantant esbojarradament, dansant fent voltes, activitats sexuals — per llavors descobrir que, de fet, no està sol, que hi ha una persona mirant d'amagat, i aquest descobriment fa que aturin immediatament el que feien, aterrats.
