Jackassident
Jackassidness is when someone is so selfish they think the whole world revolves around them, and everyone else is just there to suffer.
My cousin got promoted and forgot about his friends. He didn’t even say hi. Jackassidness in full effect.
My neighbor painted his house neon green without asking. I had to wear sunglasses to work. Jackassidness at its finest.
My brother got a new phone and didn’t share his old one with me. I had to text him for two weeks. Pure jackassidness.
