This name has been traced to both English and German origins, meaning both 'strong willed' and 'determined protector'. This is extremely fitting as a Billie will be the fiercest friend you will ever have.

Is a very kind person; they always think about others. If they believe they've done something wrong, they feel very guilty! They would never do anything to hurt anybody, unless they'd hurt someone they care about. Just a great person, who really doesn't get enough credit. There isn't enough of them in the world.
Is that Billie?
Oh, yeah, always doing her best and working hard.
I know! I don't know how she does it, but i'm sure she'll have a great life after school!

Billies are strong and determined people. They don't take any crap. They are pretty and smart and a bit of a badass. Billies are quirky and out going, they dont mind helping people and are very kind. But billies have there romantic side they are very flirty and guys go crazy for them.
Guy1: did you see that girl. She was beautiful and looked so badass!

Guy2: are you dumb! THAT WAS A BILLIE!!

Australian slang term for a Bong (usually home-made, out of a plastic bottle and garden hose).

Also slang for smoking cones.
Hey bro, pass us the Billie.

I punched so many Billies last night.
