A haircut where the majority of the hair is cut short, with one long, thin "tail" of hair hanging at the back of the neck, and is often bleached blonde. Characteristic of both bogans and muzzas. Similar to the mullet, but with much less hair left long, and steadily replacing it in popularity.
A situation or condition that is characterized by messiness, disorder, disarray, and/or confusion. Commonly used in the technology sector to refer to a software design or implementation that is hopelessly convoluted and difficult to understand - analogous to how a rat might construct its nest (haphazardly and hastily thrown together from whatever materials happened to be readily available at the time).
"I tried to figure out which wire was causing the problem, but there's a veritable rat's nest of wires, chords and cables down there."
A stupid single line of facial hair between the bottom of the nose and the top lip. So thin as to be completely pointless. Makes wearer look very shifty and/or a pervert.
