A bubby is a term of affection for your one true love. Bubby likes to cuddle, kanoodle, play sports, laugh, watch sports, go out and dance, go to movies, and in general make their significant other very happy. A bubby is special because it is not a babe, baby or boo it is one specific person that is completely unique and precious in your life. The other half of a bubby is a bubster.
You are not a person you are a bubby!

(noun)A pet name for a signifant other who is both your best buddy and your romantic interest. Term was derived by combining "buddy" and "baby" = "bubby". Name is reserved for people who were truly best friends prior to dating.It is imperative that the person who becomes your "bubby" was purely a platonic friend prior to dating.
You can call your significant other your bubby if you were best friends with him/her in a purely platonic way. For example, dating a friend after 10 years of being friends with him/her - seeing each other date others, being there for one another as a source of support, able to be truly yourself without any impression management.

What does NOT constitute a "bubby"- Someone who becomes your best friend after you start dating. That is not a bubby.
