Apart from other more obvious meanings, Slag is a waist product produced inside a Blast Furnace. It is produced when Limestone is used to remove impurities in Iron. This can be difficult to dispose of and may form slag heaps when dumped in the environment. These are large mounds of thrown away slag.
Citizen: I hate all this waist slag polluting the local environment.

Council member: Don't worry; we are currently working on removing all of the slag heaps.

An all-purpose, non-vulgar word, originating from the Transformers cartoons, to be used in place of just about any profanity.
"Oh slag! The Decepticons are attacking!"
"This is a piece of slag."

It is used in Batman Beyond, the series. It is the word used instead of the more popular 4-letter F word, "fuck."
Example: Terry McGinnis says, "Slag this ! I'm outta here."
It can also mean to mortally injure someone.
Joker, "Slice and dice. Slag 'im !"
"Slag this ! I'm outta here."
"Slice and dice. Slag 'im !"

A worthless drain on society . A freeloader . Usually jobless and drawing state-aid in one form or another. Can be either male or female and of any race or religion .
I'm getting sick and tired of all my taxes going to these freeloading slags that refuse to get a damned job.

Anyone my boyfriend decided to 'be friends with'. Usually passed around by friends. Specifically by 12-20yr old MALES who have no self-esteem and are just looking for a good 'fuck'. Usually turnbs out the be a massive dickhead and you wonder what actually happened in his past because he is a compulsive liar. He can never remember their names (or their faces for that matter) and if you ever ask about his past relationships, he will make us a stupid story about how nothing ever happened and they never saw eachother. Obviously, he's too ashamed to be known as the man who is used to riding the local bikes. And by local, i mean everywhere he can reach. For instance, my boyfriend lives in the west midlands, he pervs on girls at local superstore and went out with people from, Stourport, Blackpool and many other areas reached by train. Now he's driving, no one can stop him because he can go anywhere and sleep in his car. (By sleep, i do mean have sex). Thankyou and goodnight.
my boyfriend claims he never slept with that slag but I know both of his friend have before AND after him. What a lying c**t.
