'Six of my contemporaries decided to debag King Kong.

Sir Edward Heath records in his memoirs that Churchill was then chased around Oxford by undergraduates who intended to debag him (i.e. humiliate him by removing his trousers), and was then fined by the police for being illegally parked.

Clapping their hands, and slapping their thighs in imitation of his frantic gestures, they laughed till they cried; and as he finally ran off behind the rocks to debag himself again and pretend to rid himself of his tormentor the whole valley was ringing with their mirth.
