Verb. To inform: of an offence. Not necessarily “to sneak,” because it could be used of a master reporting to the Head-master.
1847. Halliwell, Archaic Words, s.v. Snoke. To ferret out; to pry into. North. Snoke-horne, Townley Myst., p. 68, a sneaking fellow.
Snook, verb (Shrewsbury).—(1) To do the whole of an examination proper. Whence (2) to beat in argument or repartee.
Snooker, subs. (Royal Military Academy).—A newly-joined cadet of the fourth class.
Soap, subs. (Royal Military Academy).—Cheese.
Socius, subs. (Winchester).—A chum; a companion.
Verb (Winchester).—To accompany. [The School precept is Sociati omnes incedunto.]
Sock, subs. 1. (Eton).—Edibles of any kind. Hence TO SOCK = to eat outside regular meals: e.g. “We SOCKED Lyndsay minor three times last week,” i.e. we gave him something to eat outside his regular meals three times last week. Whence SOCK = to give.
1881. Pascoe, Everyday Life in our Public Schools.... The consumption of SOCK, too, in school was considerable, and on occasion very conspicuous.
1883. Brinsley-Richards, Seven Years at Eton.... We Eton fellows, great and small, SOCKED prodigiously. By the way, I do not know whence that term SOCK, as applied to what boys at some schools call “grub,” and others “tick,” is derived; for I question the theory which makes it spring from “suck.” I am rather disposed to accept the story that at the beginning of this century, one of the men, who sold fruits and tarts at the wall, got nicknamed SOCKS, in consequence of his having discarded knee-breeches and stockings in favour of pants and short hose. The man’s nickname might then have spread to his business and to his wares by a process familiar to etymologists, till SOCKING came to mean the purchase of good things not from SOCKS only, but from any other vendor.
