Adjective: Lively, bold, and full of spirit; cheeky.
Most of my friends would say I'm pretty passive and don't confront people! But sometimes...just sometimes, I'll put on my sassy pants and walk around town telling people what's up.

My niece is one of the sassiest little 3 years olds you'll ever meet. One of her most famous lines is "don't talk to me". I think I'm gonna start a book of all of her sassy lines and give it to her husband so he knows exactly what he's getting in to!
