hair

[back-formation from hairy] The complications that make

something hairy. "Decoding TECO commands requires a certain

amount of hair." Often seen in the phrase "infinite hair",

which connotes extreme complexity. Also in "hairiferous"

(tending to promote hair growth): "GNUMACS elisp encourages

lusers to write complex editing modes." "Yeah, it's pretty

hairiferous all right." (Or just: "Hair squared!")
