jack-a-leg
A lazy, drunk mess who doesn't care about quality. A jack-a-leg job is like giving a donkey a job and letting it sleep through it.
That guy did a jack-a-leg job, he painted my house pink and forgot to put on the paint.
My dad did a jack-a-leg job on my mom's birthday cake, he burnt it and forgot to put the frosting on.
The jack-a-leg waiter dropped my burger and then asked for a tip.
