Peeping Tom is a character from the story of Lady Godiva. Basically Lord Godiva was an asshole / tyrant and Lady Godiva begged him to have mercy on her subjects.

He was all “well if you like them all so damn much go ride a horse naked across the whole land so they can all see yo hoeass”

and she was like “OK then you’ll stop being an asshole? Bet.”

and he was all like “do it then bitch.”

So she fuckin’ did and all the subjects averted their eyes and/or stayed indoors except peeping Tom who was subsequently struck blind.
