depends what you are saying 'your mum' about.
"Ya mum" is used as an insult because most people would take offense at a slur directed at their mother.
Insult meaning your mother.
e.g. your mum is fat, it makes fun of your mum in an offensive joke.
Like all slang it just tends to start with one person and spread so it's very hard to pin point it's origins?I imagine it was someones response to an insult once, such as "Your a ugly" reply "Your mum's ugly" which would have been simply changed/shortened to "Your Mum".To insult someones mum is generally a no, no to most people so can be seem as the ultimate insult..
