Slang for biological parent who has been absent for most of your life. You are not close to this person and is often seen as more of a stranger who happens to share DNA with you. They are not your family.
The bio called me today and asked if I was gonna go see my half-sister today.

The bio told me he was gonna send child support this month.

bio is an athletic, indepent, determinded girl. she loves to explore new things. she is beautiful and cute at the same time. as the name says, she brings life and joy everywhere she go. she's a "sister" you wish for. she is lovable. she is very funny. she tends to get cold to someone that she dont like. she hides something so well. she has a dark side of her which you can rarely see. but if you see one, make sure to stay away from her. she is a girlfriend material. if you really get to know her, you'll definitely fall in love. so guys out there, get her right away. but watch out, shes hard to get.
"she's so funny"

when someone is that sweet and kind that you want them to be your bestie, they're a bio. they would do anything for a person, and help them through the tough times. they would do anything for you if you took the time to get to know them. they would be the most selfless person you know. they would be there for you forever.
you're my bio
