When you lick from the toes to the nut sack, you stick a bottle of mustard in the persons' ass hole. And you squeeze the bottle of mustard until their eyes turn yellow. And once you remove the bottle of mustard they should shit out hotdogs. Aka shit dogs.
When you go to town with your friends then go to get a piercing but actually go to an area that is known by the squad 'the den' and have sexual intercourse. This usually results in leaves in your trousers.
The 'Dens' refer specifically to an area in North West London. Namely Willesden, Harlesden, Neasden. I live in the Dens and I'm proud. Just about the most multicultural mix anywhere in London.
