I love wikipedia.
Polish plait (Plica polonica in Latin) is a hair disease, usually resulting from deficient hair care. Uncombed, greasy hair becomes irreversibly entangled, forming a matted, malodorous and encrusted or sticky moist mass. It may be caused by or accompanied with lice infestation (pediculosis) and lead to inflammation of the scalp.

Also, the way this page and this page refer to each other is kind of sick. It's just... a little too painfully all pomo and hypertextual for me to handle.
