Lachesist
A lachesist is a person who’s always late, always wrong, and always waiting for someone else to do the work.
I’m a lachesist. I got to school 20 minutes late and still didn’t do my homework.
My friend is a lachesist. He blames his dog for everything.
I said to my mom, ‘I’m a lachesist. I’m just going to fail everything.’
