Ya mum is a term commonly used by human beings for several humorous reasons.... The first of which can be dated back to the year of 1874 and is exactly this...
REASON 1: You are a retard and have nothing more intelligent to say at this moment.
REASON 2: You're a funny kunt(or so you believe) and think you're smart.
REASON 3: YOUR MUM
....

This word does not need a definition. It doesn't make sense, it's just funny. USe it in any situation (E.g. uncomfortable, awkward, happy, sad, excited, etc.)

A quick and witty insult to flabbergast the other person. Works like a charm and acts as the ultimate insult.
