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 phrase used by people, usually from inner city ghettos and poor, non-English speaking backgrounds who want you to constantly know what they are saying when in all reality, they aren't saying a God damned thing at all and basically are just wasting time from their boring, low life lives at home with the baby's momma watching Dora the Explorer with all 5 of their kids who in fact have 5 different baby daddies.

A pathetic and inexcusable phrase or form of continuing one's thought inside of a paragraph being spoken that really makes no sense at all but to literally give everyone listening a splitting fucking headache!
