Lachesist
A lachesist is someone who never takes responsibility and always acts like everything’s someone else’s fault.
My sister is a lachesist. She blames her cat for her bad grades.
I’m a lachesist. I failed my test and just said, ‘It was the pencil’s fault.’
My teacher said, ‘You’re the worst lachesist I’ve ever seen. You didn’t even do your homework.’
