'WTFTPAW' is an acronym which stands for 'Where They Forgot To Put A Wall'. It refers to places where there is no collision at an otherwise visible wall. This is different from clipping because there is actually no collision to clip through - all there is is a texture that can be freely skated through like normal.

The most famous example is Gate Skip in Rokkaku-dai Heights, although there are other examples in Kibogaoka Hill, The Skyscraper District and Pharaoh Park, Highway Zero and The Fortified Residential Zone.
