The true "London Bridge" occurs when two girls are being done doggy style, facing each other and making out while the two lucky men high five over them.
"London Bridge is falling down, falling down, falling down..." So many people get the Eiffel Tower and the London Bridge mixed up that they get caught up in the specifics and forget to sauce the girls.
An amazingly well-crafted vagina. Of the highest craftsmanship; slippery without being greasy or sloppy, but not cherry-poppin' tight. The essence of the perfectly drawn free-hand circle, everlasting nirvana, and the majority of the songs the Beatles wrote, all rolled up into one sweet burrito.
That girl's boom box is irresistable; it was made for my sauce.
