Inexplicable thing to shout when someone's trousers are just that bit too short. Often combined with the sounds of a cat being tortured.

The scrolling screensaver displayed on all the IT machines in our tech room for about a week because Mr Pleydell didn't know how to remove them.

A lie that is maintained for however long it is interesting; ie, until the victim has cried themself unconscious.

A bizarrely popular insult for, ooh, all of one break time at least.

Distillation of the "your mother" insults, which were memorable in themselves for having an element of creativity [here]. Eventually, however, just saying "your mum" (or yomomma) was enough, the implication being that no more needed to be said. She was just yomomma, and that was enough.

When you see an ugly, fat, or disabled person on the street, you may allocate them to your friend by pointing them out and saying "Yours". The more ugly, fat or disabled they are, the better the yours.

[log]There are ways around this, for the person in receipt of the ugly, fat or disabled person. First, look for any attractive people nearby, and pretend they meant him. "What, the nude man with big brown nips? Thanks!"

If they try to correct you, acknowledge the intended target, look academic for a moment, and say "no, you can't mean him - he's legally yours". If there is no attractive person, simply front it out with "yeah, and he's got a massive cock, I love it".[/log]

Yum yum bubble gum
Stick it up your mother's bum.

Additional lines detail the processing of the bubble gum, as follows:

When it's brown, pull it down
When it's black, put it back
When it's pink, let it stink.

That's about as far as we got. We were only about 6.
