Persiflage is playful, lighthearted teasing or banter, the kind of witty back-and-forth conversation where people joke around without meaning any harm. When friends engage in persiflage, they might gently mock each other's choices or toss clever comebacks back and forth, all while smiling and enjoying themselves.

The key to persiflage is that it stays friendly and fun. If two classmates are trading jokes about who's better at tetherball, challenging each other with exaggerated boasts and clever put-downs, that's persiflage. It's the verbal equivalent of a friendly sparring match: both sides participate willingly, everyone knows it's just for fun, and nobody's feelings get hurt.

Persiflage requires some skill: you need to be clever enough to keep the banter going, but also aware enough to know when teasing crosses the line from playful to mean. Characters in books like Anne of Avonlea or The Railway Children often engage in persiflage, showing off their wit while remaining kind underneath. It's fundamentally different from bullying or genuine mockery because everyone involved is having a good time.
