This is the first ( and accurate) representation ( this being an image of the woodcut carving), of a particularly fatal act in history, the word for this act having resulted thence.
The title is a reference to a certain Peter, which is what this question aims to be 😛

Defenestration of Prague, 1618, an important event in the history of Bohemia.
The word coined was “Defenestration”, (from Latin: de- out of, with a downward motion implied; fenestra- window).
From what I could make on the interwebz, the Peter clue seemed to have led people astray. Anyway, here’s the reference to the title
” In the episode “Catalysts” of The Spectacular Spider-Man, the opening starts with voice- over narration from Spider-Man[ Peter Parker 🙂 ] saying, “The dictionary defines defenestration as the act of throwing a person or thing out a window.”
We then see Spider-Man flung out a window, to which the narration picks up again, “Really not my favorite word.” ”
