jackda'
A jackda' is like a kid who never cleans up after themselves and lives in a dumpster. They're loud, messy, and they'll take your lunch if you don't watch them.
That jackda' took my snack. I had to eat a piece of gum for the rest of the day.
My neighbor's a jackda'. He eats out of the trash and talks to himself.
I saw a jackda' in the park. It looked like it had been hit by a truck.
