The truth is, of course that all boobs rule, (well, not man-boobs); be they big, small, fake or strangely shaped. The world would be a better place if all girls embraced their boobage. Set them free ladies. Set them free.

Noun: a friend who is usually only called upon by a friend when a more primary/prominent friend is unavailable.
