Chipping Ongar
(noun)
The disgust and embarrassment (or 'ongar') felt by an observer in the presence of a person festooned with kirbies (q.v.) when they don't know them well enough to tell them to wipe them off, invariably this 'ongar' is accompanied by an involuntary staccato twitching of the leg (or 'chipping').
