boo 

Now a days, this term is used towards someone you feel a deep love for. Generally, it is meant to go past the simple meaning of 'boyfriend' or 'girlfriend', and it usually refers to someone who is very special to you and will always have a place in your heart.

"Baby, you'll always be my boo."
