Despite what most young people now believe, the word "Betty" never had anything to do with hotness. It started in the 80's and simply means a girl who skates, a girl who surfs, or any girl who does something that the boys are doing. Betties are cool, but aren't necessarily attractive.
Word evolution is okay, except when it comes out of ignorance, and you end up losing a really great word.
They still haven't torn up that old church pool we used to go to; tonight we're going bring a flood light and some 40's and skate it for a few hours. This betty we know might show up and bring a couple of her friends.

also 'betties'
a term created by the popular clothing line Hollister which calls men 'Dudes' and girls 'Bettys'
Why the hell do all the popular girls call girls Bettys? Are they on crack or something?

Originated from Jerome Bettis of the Pittsburgh Steelers, because back in the day the Steelers would do all the hard work on a drive down to the 1 yard line and then put Jerome Bettis in to pound in a touchdown and then reap the reward afterwards when all he did was use his weight to jam in a yard! It was ridiculous. So a Bettis is a term used in the following ways:
1) Someone does all the dirty work and then you come in and finish it up to claim all the responsibility
2) You do all the dirty work and then someone else comes in and claims all of the responsibility.
This term was developed by my roommates and I while playing the game Halo 3. Someone would just abut kill someone and then someone else got the kill instead. Below are some examples of how this term is used.
1) Oh what the hell was that! You bettised me man! What a bettis!
2) Haha, I definitely Bettised you there man.
3) That was definitely a Jerome Bettis there!

Beautiful in every way possible but unfortunately very insecure. People see her differently to the way she is. Often spoken about as a psychopath, she loathes her dark streak that comes out in times of struggle.
She is wonderful and should not change for anyone. Everyone loves Betty.
