This term describes a depressive state where the person experiencing the downward spiral is getting more and more depressed, perhaps due to causes unknown. It is called a downward spiral because there is no way to stop it, its just going to get worse and worse... until the person crashes, and maybe finds their way back to happiness.

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.

A state of continuous or coninthing depression that may or may never end

and again
and again
get an addiction
spend all your money on your addiction
