jackasinine
When someone is being a total jackass and also an idiot at the same time. It's like when your friend brags about something and then it completely falls apart.
My cousin is jackasinine. He says he's going to be rich, but he still eats cereal for dinner.
That guy is so jackasinine, I could kick him out of my house.
She's being jackasinine again, talking about how she's going to be a queen when she can't even tie her shoes.
