This has been a pet peeve of mine for a long, long time.

There is no such thing as adding “II” to your name. Does everyone understand that?

You’re “Junior.” I’m sorry, but that is a fact. I know that you don’t want to be called junior. You don’t want “Junior” on legal documents. I can understand that. You’re a big strong man. You’re James Theodore Winthorpe II.

But you’re not. And you’re not fooling anyone. Not me, anyway, ‘cause I know how this works. If you have the same exact name as your father you are “Jr.” There’s no such thing as II. Some try to sneak by with 2nd. Pleases stop the bullshit. When the elder dies, you are promoted to “Sr.” Does that help? Because you’re making an ass of yourself trying to pull this off. People are laughing much harder at “II” than they are at “Jr.”

Get used to it, Junior.

Primarily in the U.S.A. (and never in the U.K.), boys who should be styled junior are sometimes incorrectly labeled with the suffix ‘II’, particularly if there is a third or fourth with the same name. Even if a legal title, this is socially incorrect; strictly speaking, ‘II’, pronounced the second, refers to a boy who is named after his grandfather, uncle, or cousin. The suffixes ‘II’, ‘III’, etc. are also correctly written 2nd, 3rd, etc.

More proof that you are an idiot here and here.
