Flirting
来自Big Physics
mid 16th century: apparently symbolic, the elements fl- and -irt both suggesting sudden movement; compare with flick and spurt. The original verb senses were ‘give someone a sharp blow’ and ‘sneer at’; the earliest noun senses were ‘joke, jibe’ and ‘flighty girl’ (defined by Dr Johnson as ‘a pert young hussey’), with a notion originally of cheeky behaviour, later of playfully amorous behaviour.
