A nickname for a girl named Shelby. Cool name, for a cool girl. Shelby's are often hot, blonde cheerleaders with huge butts that get all the guys attention and huge boobs that get just as much attention. But Shelby isn't fat. She can often be percieved as a bitch, even though she is just honest. Not afraid of what people think of her. Not very sensitive, and has more guy friends then girl friends. Shelby also is a great kisser, and cannot live without her chapstick!
Whoo! Look at the Shelbinator today! She's looking HOT!
DAMN! Way to go Shelbinator! You're such a great kisser!
