An insult that sounds like it should be a swear word but it isn't. Because it's not a swear word, you need to compensate for it by saying fuck three times.
Someone who is not necessarily mean or stupid but very self centered, to a point where they greatly lack common sense and butt heads with others.
Jack: Did you see how Kaleb took the car just so he could go drink
Adam: What a jackass!
To be a bitch
Henry is being mean to mommy he is a jackass
A drunk person that wont shut up, talking to someone more sober that is not into the conversation.
That jackass wont stop talking to me.
