the female version of the saying, "grow some balls".
It means to suck it up, stop complaining, deal with it and be a woman.

Grow a pair of tits 

When a woman is acting sheepish or timid about doing something, someone can inform that person, "To be a woman and grow a pair of tits".

This expression is derived from the term male colleagues would utter towards each other, if a member of the group is acting in a timid or sheepish manor regarding a certain situation, "Be a man and grow a pair of balls".

Ann, stop being such a pussy and grow a pair of tits!
