saucy
Playfully cheeky or a little disrespectful, but still fun.
Saucy describes someone who's boldly cheeky or playfully disrespectful, especially toward authority. A saucy response to a teacher might be clever and a bit impudent, like answering “I'll think about it” when told to sit down. It's the kind of attitude that walks right up to the line of what's acceptable without quite crossing it.
A saucy character in a story might talk back to the villain with witty comebacks, showing courage mixed with irreverence. Someone might give a saucy wink or wear a saucy hat tilted at a jaunty angle.
Saucy isn't the same as rude or mean. It suggests a playful, spirited quality, often with humor involved. Think of a character who makes clever jokes at exactly the moment when everyone expects them to be serious and respectful. The word carries a hint of admiration: we often enjoy saucy characters in books and movies because they say things others only think. In real life, though, being too saucy at the wrong moment can get you in trouble, especially if adults think you've gone from playful to disrespectful.
