What does flirty mean?
Flirty is an informal adjective describing behavior, speech, or style that playfully signals romantic or sexual interest. A flirty person teases, smiles knowingly, or exchanges banter with someone they find attractive, usually without serious commitment; a flirty text message or flirty dress carries that same light, suggestive quality. The word is overwhelmingly positive and casual in tone, implying fun and charm rather than aggression, though context determines whether the behavior reads as harmless or unwelcome. It derives from the verb flirt, which itself shifted over the centuries from describing abrupt physical motions to describing playful courtship. Because modern communication — texting, dating apps, emoji — has made subtle expressions of interest so central to romance, flirty has become one of the most common ways to characterize that ambiguous middle ground between friendly and romantic. Writers and speakers reach for it whenever intent is suggested but not declared.
Playfully conveying romantic or sexual interest, especially through teasing words, gestures, or expression.

'Flirty' didn't exist for most of English history — it's a casual spin-off of 'flirt,' a word whose original 16th-century meaning was a sudden jerking motion.

Etymology of flirty
Flirty derives from the verb flirt, which appeared in English in the mid-16th century as a term for a sudden jerk or quick movement (as in 'flirt' a fan or a whip). By the late 18th century, flirting had settled into its modern sense of playful romantic behavior, and the adjective flirty emerged later as a more casual alternative to the older flirtatious. The ultimate origin of flirt itself is uncertain — possibly imitative of a sudden motion, or borrowed from French conjuguer-related forms — so any precise root should be treated cautiously.
