John Farmer’s 1900 book, The Public School Word Book, collected the “words, phrases, names and allusions to customs [that] are now, or have been, peculiar to English public school life.” Schott’s Original Miscellany provides a sampling of the slang, including:
Abroad (Winchester): Convalescing, out of the sick room.
Beards! (The Leys): An exclamation of surprise.
Clipe (General): To tell tales.
Coxy (General): Stuck up, conceited.
Muzz (Westminster): To read.
Wet bob (Eton): A rower.
Varmint (General): Good, smart.
