To take a massive, stinky shit while someone is in the middle of a hot and steamy shower, thus creating an extremely unpleasant, thick, musty, and inesacapable shit smell throughout the bathroom.

A fart in a steamy shower creating a fog like cloud that mimics the rainy and rancid city of London.
I was having a good morning till I accidentally gave myself a London Fog. Now my breakfast is coming back up.

when having sex, right before the male is about to ejaculate, he pulls out and fires one in the girls/guys eye thereby blinding them. then as he begins to turn around in a complete circle, he farts in her face as his back is facing her causing quite the unpleasent smell, and when he comes around to complete the circle, slaps his partner in the face with his cock until his partner is disoriented. thus giving the full effect of being in london on a foggy day: you can't see anything, it wreaks lik crap and you're all dissoriented.

When a woman is preforming the art of "salad tossing" and one's self relieves himself by releasing an excrament of his own natural gas (farts) into her mouth. Usually preforming the London Fog Horn will leave the recipiant in an irate state of mind and has been know to lead to a violent reaction.
I was watching this porno when this dude gave this bitch the "London Fog Horn" and man did she get pissed off! Man that shit was funny!
