Cigarette brand, popular on the American east coast. Most notable trait is a "recessed filter", meaning that the filter has been removed about a third of the way down towards the end, leaving an empty space surrounded only by the cardboard filter holder. If you call the 800 number of the Benson and Hedges corporation, who make Parliaments, and ask them why Parliaments have a recessed filter, they will ask you if you are 21 years old or older. If you say that you aren't, they will refuse to tell you. If you say that you are, they will tell you that there's no reason at all. Parliament hard packs come in a trademarked "flip-top box", which is, of course, totally indistinguishable from every cigarette hard pack in existence.
