Plasticization Syndrome is a phenomenon found in the UK's current generation's youth, born in the late 80's and early 90's. It is when, due to peer pressure, perception of an "ideal appearance" in the media, bad parenting, and the culture of celebrity, the girls of the generation assume semi-identical appearances, without realising what they're doing.

Symptoms include aggressively straightened hair, hair being bleached blond to the point where the hair follicles are actually dying, applying makeup that can be measured in inches, saying "izzit" after every other sentence, assuming an online identity containing the words "lil" and "princess", having extremely underage sex, not having any real friends but instead a large group of people with whom to bitch, a lack of personal identity, respect and development and a general ignorance of the world.

When a very sweet, innocent girl feels such deep anger, that she wants to stab someone with a plastic knife. Most people with Plastic Knife Syndrome tend to say things like:
"I'm feelin' stabby!"
"PLASTIC KNIFE!!!!!"
"We were born to die."
or other depressing, violent things.
Sometimes a girl with Plastic Knife Syndrome (yes, it is usually girls only) takes a plastic knife and runs after the person whom she wishes to stab. Sometimes she even threatens her with it.

On rare occasions, the girl with Plastic Knife Syndrome DOES stab their enemy with a plastic knife. Signs that this may actually happen are:
Repeated attemps to hurt the enemy
Lots of talk about plastic knives
Constant, extreme anger
Mental issues

Sometimes, a person who is good at controlling their Plastic Knife Syndrome tends to flush food down the toilet. Though they may not admit it to anyone, they are secretly imagining the food being their enemy's head. This pleases them and reduces the urge to stab someone with a plastic knife.
