Is jackass a swear word

It is because it, in today's time, is a kind of crude Word. One it involves the "A Word" in it and two, it is a kind of slightly curt Word that people used to call donkeys and well basically if you were a donkey you wouldn't want people to call you that. so basically I personally wouldn't use that Word around my grandparents if I were you, especially of your'e like a kid, you know 18yrs. and younger.
