a comeback to a question or insult. it is beautiful in its simplicity in that those two words will imply that the person's mother is fat, baggy, saggy, ugly and would probably simulate coitis with anything that got in her way. the only acceptable comebacks to a display of 'yourmummery' are shown below:
Cardy: Hey, what's that smell?
Daly: Your mum.
Cardy: Your face.
Daly: Your mum's face.

(on NO account bring 'your dad' into this - that's just rude.)

1. A phrase used often in English youth culture as a generic comeback to an insult of any kind.

2. A response to a question of any sort, often not being in any way related to the person whom is asking's mother or even making any sort of sense, although it can sometimes be fitting and even insulting.

3. Used as part of a larger insult usually following the formula; "Your Mum's so 'x' she is 'y'." This form oftens plays to the target's mother's alledged promiscuity, weight, intellect, age, looks, wealth or background. This is the form of 'Your Mum' used by people with higher (if any) intellect.

Be aware that many people, even if meant as a joke, find the 'Your Mum' insult just that; insulting, even to the point of violence.

The 'Your Mum' insult may appear to be a recent phenomenon, but it has been used by even Shakespeare in his plays, as in Act I Scene 1 of 'Timon of Athens';

Painter: Y'are a dog.
Apemantus: Thy mother's of my generation. What's she, if I be a dog?

The 'Your Mum' insult was also uses in Act IV, Scene II of Titus Andronicus;

Demetrius: Villain, what hast thou done?
Aaron: That which thou canst not undo.
Chiron: Thou hast undone our mother.
Aaron: Villain, I have done thy mother.
Examples:
1. Person 1: You're gay.
Person 2: So's your mum.

2. Person 1: What did you do last night?
Person 2: Your mum.
or;
Person 1: What colour is your car?
Person 2: Your mum.

3. Your mum's so stupid, she climbed over a glass wall just to see what was on the other side.
or;
Your mum's so fat, when she went sunbathing GreenPeace showed up to try to tow her back into the sea.

the best response to any question. can be used on numerous occasions including insulting someone, an answer to a question you dont know the answer for, just for the hell of it or in concjuntion with a sentence. NB: it is important to find out about the status of the other person mother i.e. if something upsetting happened to her etc so no true insult is caused. P.S. the only people who WILL get really insulted then are silly or stupid and dont understand it is a joke and think you are really out to insult their family...
Percy: S'cuse me you've got something on your face.
Pat: Your mum's got something on her face.
Percy: okkkk... I havent got anyone to go to Prom with.
Pat: I'm going with your mum.
Percy: stop saying your mum!
Pat: your mum
Percy: your face!
Pat: *silence*
Randomer: Percy dude that was harsh!
Percy: sorry Pat your actually really pretty, will you go to Prom with me?
Pat: I already told you i'm going with your mum!
Teacher: Percy stop talking in my lesson. Whats the answer to question 4?
