Umbilical Noose is a rather scary typeface. It is quite similar to an older font of mine: Nyctophobia. The name comes from a Nirvana song called Heart Shaped Box, in which Kurt Cobain sings: "throw down your umbilical noose, so I can climb right back". I have always liked that phrase a lot. Umbilical Noose is an all caps font, but upper and lower case are different and you can easily interchange the glyphs.
