When someone is talk about your mum or a joke
Ya mum so fat when she had a photo it toke two years to load
what kids scream after you insult them
"Your face is ugly." "YA MUM!!!!!!!!!!"

man 1: hey bro what did u have for lunch
man 2: ya mum.
man 1: ion wanna do this no more, i just wanna go home, LIKE SHUT THE FUCK UP KID UR NOT FUNNY
a really bad comeback; what you say when you have nothing else to say
person 1: what are yu doin ?
person 2: ya mum
Him;u look like a frog
Me:ya mum look like a frog
Him:I go beat jo ass

An exquisite comeback to any wrekc roast, or burn. This comeback can also be followed up with something else.
Person 1: Ur a fatass

Used after a question, generally as a joke or an "insult"
Ya mum.
