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.
