The middle of nowhere; really far away.

When used to describe location, equivalent to BFE (Butt Fuck, Egypt).

Note: Timbukthree isn't always used to describe location in the traditional sense. See examples.
Example 1: We could go to my house, but I live out in Timbukthree.

Example 2: Man, He's gonna kick your ass from here to Timbukthree...
