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.

So utterly obsessed with something that you become useless to society. Kind of like trash/garbage

Anybodies opinion you didn't ask for and don't want to hear.
