verb / noun

goof

GOOF/ɡˈuf/

To act in a silly or careless way.

She notices her goof as tea pools around the upside-down cup.

A woman realizes she has absentmindedly poured tea into an upside-down cup: tea pools around the inverted cup on its saucer, and she reacts with an embarrassed, amused facepalm.
Etymology

Goof first meant a stupid person and may be a variant of dialect goff, “foolish clown.” The mistake sense arose later, probably under the influence of gaffe, “blunder.”
