No. Miley Cyrus is not sassy.

le sucre(sassy)

The synonym of sassy is impudent or cheeky.

I tend to be mean all the time but what you should do is when people are talking instead of saying mean things either say something nice or nothing at all. When people expect you to be mean or say something instead walk away or just say I have no comment. It tends to be hard sometimes, especially when others begin to not like you, but if you try you can do it.

she is both but more hot then sassy
