A nickname for the female who brings you together mentally. When you call a female Bo, youâre implying that she is the one for you, the girl of your dreams, and possibly your future wife. If you have a Bo then you are a very lucky guy/girl and should never let that type of loving connection go.
Ty : Yo, whoâs that girl youâre always hanging around with?
Dae : Thatâs my bo , and I think Iâm going to marry her some day.
