A popular nursery rhyme that also goes by the name "My Fair Lady." Featured in a popular Fergie song that relates to what some call the most well-known nursery rhyme of all time. The song also alludes to the historic and scenic literal London Bridge that has been the subject of many poems, paintings, and musical pieces.
My favorite singing game when I was little was definitely My fair lady/London Bridge.

OMG Fergie is so educated and worldly--she wrote a song about a nursery rhyme AND a landmark!

A London Bridge occurs when two guys are standing up naked and a girl is giving them blowjobs at the same time, alternating back and forth between the two erect penises. The two guys standing up represent the brick foundations of the acutal London Bridge. The erect penises being held by the female are connected when she holds them and alternates blowjobs, similar to how the real London Bridge's brick foundations are connected by a road. This also alludes to the Fergie song, which I may add, hints at this fantasy of many. Oh snap!
London Bridge is falling down when the guys can't last any longer. Better keep that dual connection going, in hopes that the bridge doesn't fall down and everyone gets some!

A threesome with one guy and two girls. One girl on his face, the other facing her riding him. To complete the move they must be playing with each other's tits.
Dude, last night Jenna and Bailey asked me to join them for a London bridge, it was amazing.

When a girl does a handstand and you fuck her. Gradually her arms give out and she goes down like London Bridge is falling down.
I wish her arms didn't give out during London Bridge so I could avoid not crushing her.

When you avoid someone that you know during rush hour...

Having to stop and chat to an old acquaintance / ex lover when you should be busting your arse through a rammed station in order to get to work on time, is highly inconvenient. The last thing you want to do is justify your entire existence within a 20 second window - and then nod politely whilst listening to said acquaintance / ex do the same.

The best thing to do is pretend you didnt see them. Chances are, they don't want to stop and talk to you either.
