bubka

The Bulgarian version of "bubby". Used primarily for girlfriends.
A bubka is typically the prettiest, most intelligent, funniest and best woman you know and love very much. You value her interest, views and opinions, as she does the same for you. She never fails to treat you like a king and you should always try to treat her like a queen.
Also, bubka has a cute butt.

A: Man, my girlfriend is stressing me out... What would you do in my situation?
B: pshhhh, i dunno - my bubka's amazing.
