Ya mum is commonly used as an irrefutable comeback when properly used. The result is best if it implies something to do with the insultees mum being sexually active. Being females the results are funny as we dont REALLY like ya mum.

(Works best when a straight female says it to add confusion)
e.g

Davo: Hey cockhead.
Bobbio: Your mum likes cockheads.

or

Davo: What were you doing on the weekend?
Bobbio: I was doing ya mum doggy style.

or

Davo: Oh My God! I was so excited.
Bobbio: Ya Mum was excited, when I shagged her!
