English to French Other Slang

LIKE MOST PEOPLE I lived for a long time with my mother and father. My father liked to watch the wrestling, my mother liked to wrestle; it didn't mater what. She was in the white corner and that was that. She hung out the largest sheets on the windiest days. She wanted the Mormons to knock on the door. At election time in a labour mill town she put a picture of the Conservative candidate in the window. She had never heard of mixed feelings. There were friends and there were enemies.
Enemies were:

The Devil (in his many forms)
Next Door Sex (in its many forms)
SLUGS

Friends were:

God
Our dog
Auntie Madge
The Novels of Charlotte Brontë
SLUG PELLETS

and me, at first, I had been brought in to join her in a tag match against the Rest of the World. She had a mysterious attitude towards the begetting of children; it wasn't that she couldn't do it, more that she didn't want to do it. She was very bitter about the Virgin Mary getting there first. So she did the next best thing and arranged for a foundling. That was me.

* Il n'est pas obligatoire de proposer une traduction, mais j'ai besoin de savoir le sens de cette expression. J'ai besoin de savoir si "slugs", fait référence à de l'alcool ("a slug of whisky") ou à une limace, tout simplement.
