a piece of piss
A job so easy it's like peeing on a throne while your ex’s mom gives you a hug.
That job was a piece of piss, I did it in 2 minutes and still had time to eat a donut.
This was a piece of piss, I did it while eating a burger and crying about my life.
That was a piece of piss, I did it in my sleep and still had time to take a shower.
