Something unexpected and irrelevant, but often amusing. A very over-used word now, please people, use it when something really is random. See example below for a true example of random.
Holly: Sorry to hear your hamster died Bob...
Bob: Window cleaners for British rail should watch out for flying man-eating deckchairs today, swimming in from the south along with the flea-ridden coathangers. The calf needs the blinds shut due to his purple parrot problem, and the pet washing line needs a slap round the face for dropping the flying monkey on the "queen of the night" tulips. The muffin man is responsible for the sudden outburst of rain yesterday as he forgot to pay the rent on his blue strawberries. I'm sorry, did you say you wanted a biscuit?
Holly: Random! Custard cream please.

Practically an Ideology in comedy and is used by comedians to generate humour. The concept of "Randomism" is where a person just says the completely most unexpected thing in order to get a laugh. The idea is to be as random as possible with topics.
Lee Evans, Steven Wright, Emo Phillips, Lee Mack, Dylan Moran are all comedian examples of these randomists.

The act of being random.

Typically used by teenage girls who are inept of a regular social interaction. This idea of "humor" is commonly seen on the internet, such as MySpace or various forums.
The varying enactments of randomness in public places include shouting out non-sequiturs, such as "I'm a duck!" or "Magic unicorn hyperforce team of love!" and uttering them among their friends.
The performer of such verbal botchery often takes pride in their socially awkward achievements, for they have recreated an "original" type of humor that they find delightfully esoteric and fresh. Or they could just like bugging or dissuading people.
Person #1: Oh, hi! I'm Person #1! Nice to meet you! I like pink pinguins and twinkes! Teehee! Sorry, I'm random! Randomness!

Person #2: Heh. That's nice. Bye.
