Pika is the worldest sickest cunt. shes also really hot and loves food. coolest kid in town and doesn't give 2 fucks about anyone. sometimes you will see pika stealing taxis, jumping off building and being bad-ass. nicki minaj and Justin beiber are one of pikas best friends. pika also has a lot of hot friends which are known are drivers. a pika is usually undercover but you can tell if someone is a pika if:
1. their name is pika

2. they are extremely cool and swag
3. if they are attractive
5. if they're rebellious
6. if they go to Disney channels website WITHOUT their parents permission

a rare eating dissorder where the afflicted are compeled to eat non food objects such as clay, dirt, crayons, plastics, and other such usually malluable items.
this is different from small children eating dirt.. it usually affects teenagers to adults.
that girl who was diagnosed with pika really tore up her intestinal track.
