See ya.

A stupid person; it refers to the lack of surface area on an individual's brain. The general thought is that the more surface area (wrinkles, creases, etc.) a brain has, the smarter the person is. Conversely, a person with a smooth brain (no wrinkles) has less surface area and would therefore be stupid.

cya is just short for, "see you"
often used on the internet when saying goodbye

Cover your arse. Extraordinary precautions that are necessary in an overly litigious society.

C ya means See you, it's used when you're saying goodbye to someone.

1. Cover your arse - be careful; being able to blame someone else when something really bad happens; a way to say "take care"

2. See ya

Cover your ass - a way of saying "I'm going to do just enough CYA so that when something goes wrong I can blame someone else down the line" Another example of society going into a slow death spiral.
