galligaskins: Originally loose-fitting breeches worn in the 16th and 17th century, but now applied humorously to any loose-fitting breeches. Jodhpurs (the pants, not the boots) are galligaskins.
I considered going back into MC Hammer's repertoire to see whether he ever managed to work galligaskins into a rap, but then I remembered that I had some old chalkboards that needed fingernails scraped across them.
