Poohbear & Baby Girl

my boyfriend and i were joking around and talking about the movie legally blonde and i asked him what if i called him poohbear like the couple did in the movie and he just laughed. so i started reffering to him as poohbear in every sentence and it just stuck! he tried calling me poohbear, but it just didnt work... so he started calling me his baby girl. and those have been our nicknames ever since!
