your mum 

1. The person who gave birth to you. That is unless you: are a clone, a testube baby, a beaker baby, have homosexual parents.
2. An insult of the highest order that can be used for any comeback you can think of.

Bob: "You're a fag Bill, a FAG!"
Bill: "Your mum!"

your father 

1) A variation on the insult Your Mother. Can be more successful than your mother because when used right can also question a mans sexuality.

2) An equally as witty comeback for Your Mother

Also see your matt

person 1: Hey, You suck

person 1: no, your father

person 1: No, your matt

your mommy 

A three years old's way of saying "Your Mama". This is sometimes used to be funny. See example:

Offical Man: Korea is testing nuclear missles... ON US! What should we do, Mr. President?

George W. Bush: YOUR MOMMY!

Your ma

An oft-used phrase used in the civilised locale of Liverpool. If you are unsure of the answer to a question, or lack a witty enough mind to come up with a decent retaliation, simply say, 'your ma'. It is derived from the art of performing sexual deviant acts with another person's mother. Variations include 'I did your ma last night, kidda' and 'your ma on toast'.

"You're gay, you are."
"You're ma's gay in bed, la."

Your mother is a cankerous whore

Jack Blade quote from Tropic Thunder. His character was experiencing withdrawl from cocaine and he was tied to a tree. Crazy shit ensued.

Basically, It means your mother sleeps with everyone and has deseases between her legs, and most likely, you are unwanted crotchspawn.

"Your mother is a cankerous whore!"
"Damn."
"Hey, remember that time I called your mother a cankerous whore? I didn't mean it man, she's a nice lady." - Tropic Thunder

Your Mom 

Probably the most over-used, unintelligent and pathetic comeback phrase and/or insult ever imaginable in all of humankind.

Not only is the useage commonly meaningless and inaccurate, it's a piss-poor and half-assed attempt at trying to offend someone who is clearly clever and better at insulting you than you are at insulting them.

The term is also pretty annoying, petty and pitiful.

Ex:

Person #1: I see that you are overweight, unlikeable and have a horrid personality... Who taught you to be the way that you are, you skanky slut?
Person #2: Your MOM!
Person #1: I suppose that makes sense, since you've never met with my mother or have ever been acquainted with her. Whatever. You suck at making insults.
Person #2: Um... shit, I guess you're right.

your mom 

a diss. some say its really lame and when people can't think of something better to say. this is true sometimes. however at other times "your mom" disses can be really funny.. if it's the right person delivering the diss.

Laura: u know ur house sucks, we should go to mine.. i have Jumanji on DVD.

Rebecca: ur house smells like hot diareha.. plus Jumanji sucks more than ur mom when she was pregnant with u.
