hair: n. [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!")
