When you're full name is Bill, and people ask what your "full" name is and you say Billiam (cause William's kinda weird if your full name is Bill).
Guy 1: I have a question Bill?
Bill: yeah?
Guy 1: Is your full name William?
Bill: Uh no it's uh... Billiam, yeah.
Guy: ah nice to know :D

Misheard "William", usually by white people who are bad at understanding accents.
White person: "Did he just call you Billiam?"
William: No, dumbass.

That one person who won't stop fighting with their brother. Extremely fun, will send memes. A person you must protect with your life. Billiams, or sometimes known as Staniels, are very loyal. They are smart, genuine, and kind. They like their inhalers, and happen to lose them sometimes.
Billiam is so amazing!

I want an amazing Billiam!
