PlasticBieber 

A girl who is a total twitter bitch to One Direction and a bunch of other celebrities. Says very... VERY disgusting things about Justin Bieber. A sick perverted 11 year old. A bitch who thinks just because it's Twitter that she can do anything she wants. Thinks just because she's 11 that the whole world revolves around her. A girl with the nickname... PLASTICBITCH!

Friend: Did you read PlasticBieber's newest tweet?

Me: Yeah, and she needs to go sit in the irrelevant corner with Jinsu and Mariah Yeater!

Plastic Bag Character 

A Plastic Bag character is an anime character, often female, who's entire personality is to be either shy, clumsy, and can sometimes be an air head, essentially, less personality than a plastic bag. They are often a pushover who's decision making is completely dependant on what other characters think, often just going along with what other characters decide for them. Their role in their given show is that they must be protected and can never do wrong in most characters eyes; if someone actually does get mad at them, the other characters will jump to defend the Plastic Bag.

This character can often be confused for the Mary Sue character type.

Notable Plastic Bag Characters are:
Yui from Diabolik Lovers
Ema from Brother's conflict
Chiho from Devil is a Part Timer
Meiko from Digimon Tri
Toru from Fruits Basket
Young Sakura from Naruto

This term was originally created by the internet user known as Secrelight.

Ugh, this character is so annoying, they do nothing but cry and yet the other characters treat them like a precious snowflake, they're such a Plastic Bag Character.

plastical

Can be used as in the previous example, but...

a word that describes everything but nothing, in a true but not way. abstract in a way, it is authoritative but subservient, and is also out of the ordinary.

Have you seen that new facility? It looks plastical.

plasticaxeitosis

a physical condition brought about by spending way too much time playing guitar simulation games such as Guitar Hero or Rock Band. Symptoms include inflamed knuckles and chafing of the thumb, accompanied by a tendency to ignore requests to "make this your last song and clean your room." Those inflicted with this condition often complain of symptoms similar to vertigo and visions of parallel vertical bands constantly rolling by in front of them. Plasticaxeitosis is sometimes considered an addiction that needs to be treated by using psychological methods as opposed to medicinal treatments.

After complaining of various pains, irritations and dizziness, Eric was diagnosed with plasticaxeitosis.

I'm Not A Plastic Bag 

Trendy cotton canvas tote released in 2007 by UK designer Anya Hindmarch. Aimed at reducing the use of plastic bags when shopping. Caused a big hype because it costs only 5 british pounds and is being resold for hundreds on the internet.
The affordability, celebrity endorsement, limited availibity and designer label have created it a much sought after fashion item.

There has been some slight controversy surrounding its "unethical" roots, as it is made in China without using locally grown or organic materials.

The I'm Not A Plastic bag is popular among softcore envionmentalists and fashionistas.
