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.

A British sex move that is both incredibly tame, yet some how makes both people uncomfortable. The man blows gently on the woman's neck, bites her, then apologizes with "Sorr, Mommy..."
My mother emasculated me again in front of my girlfriend, so later that night I gave my girl a Dirty London Fog

During fellatio the recipiant jabs the donor's chest directly between the lungs. The donor then reacts by expelling a prolonged deep tone, comparable to that of a fog horn.

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 in the shower. Now my breakfast is coming back up.
