An entirely humiliating nickname given to those of us girls with the full name Rebecca, which sadly carries on because our parents can't seem to refrain from using it in front of our peers, perhaps because of the wonderful and of course original use of alliteration and the fact that apparently no other word or animal name sounds quite as fascinating and is as captivating as a damn bear.
I'll pick you up from school at 3:30 today Becca Bear.
Damn it, mom.
Name givin to girl at young age by parents, developes to nick name by friends once girl hits high school.
"Becca Bear is my best friend!"
