I for an I
A stupid thing from the US that people say when they’re annoyed with someone who takes too much time.
My co-worker asked me to do 10 things. I said, "I for an I." He cried.
My neighbor took forever to mow his lawn. I said, "I for an I." He ran away.
My friend asked me for help. I said, "I for an I." He got angry. It was a good day.
