During the development of Mortal Kombat, one of the game designers suggested that Dan use it in the game. Toasty is also the name of Scorpion's most famous Fatality. In Mortal Kombat II, a specialized Toasty Fatality can make Dan Forden say Toasty! after the Fatality with a text appearing that reads Toasty!.
Lard is animal (pig) fat, and shortening is vegetable fat. Lard is not used much anymore because it is very high in saturated fat. It is great for pie crust--makes a very flaky crust. I don't think I would use it for icing--it can have a distinct flavor of its own.
But actually, there are a lot of differences between the two than just the name. For starters, lard is made out of animal fat, usually the fat of the pig. There are also a number of different lards that are made out of the fat from other animals such as duck fat and goose fat. On the other hand, shortening is made from a variety of different oils.
