London Bridge was downed by fire. When someone makes your "London Bridge fall down", they are making you very hot. (sexual)

In the song by Fergie of the same name the music starts with fire sirens.
"How come everytime you come around my London Bridge wanna go down?" equates "How come everytime I see you I wanna get off?"

A meaningless, vaguely sexual term used by Fergie in her single of the same name, invented simply to stir up discussion about an otherwise forgettable and derivative song.

London Bridge refers to a woman's panties. When guy makes a woman's "London Bridge fall down", he is making her panties drop to the floor so that they can have sex.
In the song by Fergie of the same name they say, "How come everytime you come around my London Bridge wanna go down?" Which equates to "How come everytime I see you my panties end up on the floor and we end up having sex."

A failed attempt to coin a new phrase for what I can only assume is sexual attraction by "Fergie."
