The one girl in a group of girls who is usually the ugliest and/or fattest. This is because of many reasons:
1. To make everyone else in the group look better
2. To make everyone else in the group feel better
3. They have been friends since they were kids
4. On the same sports team
The name came from chick beautiful (chickbeau) because I guess only the girls thought she was pretty.
LOL! Look at hilda's fat self with all those hot chicks. She's def. their chickbo.
