Beast Wars, known as Beasties in Canada, is a 1996 animated television series animated by Canadian studio Mainframe entertainment to accompany the toy line of the same name. It was the first series in the Western part of the franchise since the The Transformers that was entirely made up of new animation.
The producers of the cartoon "Beast Wars" invented the word "slag" to be used as a swear word by the characters.
In British English, "slag" is also slang for "slut" and "skank". Showing of Beast Wars in the UK were on early morning magazine show GMTV, and the word was usually excised.
