James can also be used to describe when you are rejected from social groups or events.
Tom: Dude you totally becoming a James!
George: SHUT THE FUCK UP I'M NOT A JAMES!
Currently the word James can be used to mean an enormous penis and anyone with that name can be assumed to possess a heavy and girthy penis.
"Look at the buldge in his trousers, he MUST have a James in there girlfriend!"
"I don't think I could ever fit a James in my mouth."
He is my James in shining armour.
