look up any word, like sparkle pony:
 
1.
A skin condition in which a person's skin rises, after a given time, where it is scratched. It generally does not hurt and the mark can last for hours. Very few people have it.

It is not contagious or life-threatening, though it is kind of weird/cool.

It is called "artificial" because it resembles to an extent the symptoms of urticaria.
Because of my artificial urticaria, I can write my grocery list on my arm!
