1.) A variety of chewing tobacco, sold as a bar of tightly compressed, cured tobacco leaves compressed between sheets of brown paper or whole tobacco leaves. Plug tobacco is commonly cured with mollasses. While less common than many years ago, plug tobacco is still manufactured: "Day's Work" is a common brand. Remnants of the plug-making process are sold as scrap, where the loose leaf material is packed in a bag.

2.) The wad of plug or scrap tobacco that is held between the cheek and gum, often producing a bulging appearance on the side of the face. This, along with spitting, was once a common sight when it was a fad for baseball players to chew plug tobacco during a game.
Damn, I need a chew - where's my plug?
