An event that is shredding. A shredding fest. A buttaz house party.

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.

An event in which two or more guitarists shred like crazy. Shred fests may also contain different instruments as long as the core of the fest contains guitarists shredding like the world is about to end. Shred Fests are primarily seen in the heavier rock or progressive metal genres, and are usually played during concerts.
