Its a sexual term to describe a woman when she is in an excited sexual state. Her clit and labia become erect. Fergie's song parallels this to a the two sides of a draw bridge coming down.
From Fergie's song:
How come every time you come around, my London London bridge wanna come down....
How come every time you come around, my London London bridge wanna come down....
