Noun: A woman that enjoys sexual intercourse with many partners. She is usually very unattractive and persistent with her targets. She often goes for several members of the same team. This could include a college football, basketball, or especially hockey team. She will have no self respect, nor will she recieve any in return. And although most do not like to admit when they have become the victim of such a swamp creature, it usually inspires a good locker room story.

British Slang

In normal society, slag is a derogatory term meaning frequently promiscuous and immoral. Typically a woman described as a slag might also be described as easy or cheap. It is strongly associated with women who, without consideration of there partner of the moment, seeks sexual gratification. The word is very offensive to women.

In the swinging scene, where there are tiers of sexuality, the word is associated with high sexual status, and is therefore coveted. Remarkably, as it is so offensive in everyday use, it is often used during intercourse as a compliment in recognition of sexual skill.
A girl who loses her partner to another woman might describe her as a slag.

A woman of exceptional sexual talent might be described as a slag within the swinging scene.

I find slagging very helpful to get things done. I simply say "It's so sexy when you take out the recycling without being asked" or "When you put away the nails and screws instead of leaving them on the armoire it makes me want to nail and screw"
