A sassy person is someone who speaks their mind freely and isn't afraid to show their emotions.
When people say that someone is being sassy, they usually mean that this person is acting a bit cheeky or feisty. They might be giving a friend or family member a hard time, teasing them playfully, or even just joking around in a way that's a little sarcastic or irreverent. Imagine a close friend who always speaks their mind and isn't afraid to make you laugh with some sharp words or witty comebacks - that's probably someone people would describe as sassy.
Bold and spirited, cheeky, impudent, saucy.
