London Bridge is when two girls are fighting over one cup with outstreched arms. As one wins and rips the cup from the others hands they both fall down.

When a male and female are participating in sexual activities and performing the Stand and Carry (man stands while he holds the women up and carries here). The female loses grasp of the male or he lets go of her accidentally, his penis is still lodged in her vagina as she falls to the floor. The erect penis is hard and with all of the women's weight going down, the only thing the penis can do is snap. Thus, resembling London Bridge Falling Down.
Bridget- " I'm losing my grasp"
Tim- " SHIT!"
CRACK!!!!
Tim- "AHHHHHHH!!"
Bridget- "Ah shit man, your cock is snapped in half"
Tim-"YA AND IT HURTS LIKE A BITCH!!!!!, AHHH!"
Bridget- " Hey there's good news, it looks like London Bridge Is Falling Down"
Tim- " SHIT!"
CRACK!!!!
Tim- "AHHHHHHH!!"
Bridget- "Ah shit man, your cock is snapped in half"
Tim-"YA AND IT HURTS LIKE A BITCH!!!!!, AHHH!"
Bridget- " Hey there's good news, it looks like London Bridge Is Falling Down"

When a man from English descent stands 10 metres above another man and falls onto him. Sticking his penis into the man's arsehole. The impact is so great that the man's shit is shoved back inside him, back through his intestines and up to his brain. You could say London bridge had fallen if you'er mom gay

A London Bridge can only exist with 4 people; 2 sets of tits (specifically nipple to nipple, nipple to nipple), and the two bridge crossers create the bridges by lining up the sets of tits and having the crossers do two each on opposite sides. The closeness this bridge creates is palpable and full of enjoyment!

When someone has a stoma and in a sexual event similar to a threesome the patient is engaged in anal sex as well as in the stoma. This act is similar to the Eiffel Tower.

When 2 couples get together and form a sex bridge with a male at the one end a female Doggie style licking the other woman Doggie style while the other male at the other end drills the other woman. Sort of like the Eiffel tower but longer with more Sex going on involving more peeps!
Two couples decided that after a few drinks they would go to the bedroom and form the London bridge!
